Gold value starts with karat, weight, current market reference price, testing, condition, and the item itself.
Quick Answer Gold value starts with three numbers: karat, gram weight, and the current gold market price. A local offer then adjusts for testing results, condition, resale demand, refining or handling cost, and whether the item is scrap, wearable jewelry, Black Hills Gold, bullion, coins, or a signed/designer piece.

Most people selling gold for the first time have the same question: how much is my gold worth? You may have jewelry, inherited items, broken gold, dental gold, class rings, coins, Black Hills Gold, or mixed precious metals, and you want to understand the basic math before bringing anything in.

This page explains how gold value is calculated. It is different from our more direct payout guide, How Much Does a Pawn Shop Pay for Gold?, which focuses more on per-gram payout examples. For the main local service page, visit Cash for Gold in Mobridge. At Larsen's Jewelry & Half Interest Pawn, we test and weigh items in front of you, explain what we are seeing, and let you decide with no pressure.

How Gold Value Starts: Karat and Weight

Every gold evaluation starts with two basic numbers: purity and weight. Everything else, including design, age, brand, condition, resale demand, or whether the item is broken, can affect how a piece is handled, but purity and weight are the starting point for understanding the metal value of gold jewelry.

Karat — Gold Purity

Karat tells you how much of the piece is actually gold. Pure gold is 24 karat. Most jewelry is made from gold alloyed with other metals for durability, which is why 10k, 14k, and 18k stamps are common on rings, chains, earrings, and bracelets.

24k 99.9% Pure gold; more common in bullion than everyday jewelry
22k 91.6% High-purity gold; sometimes seen in international jewelry and coins
18k 75.0% Common in finer jewelry, designer pieces, and some older items
14k 58.3% One of the most common karats in American jewelry
10k 41.7% Common in class rings, everyday jewelry, and durable pieces

To find the karat stamp on a ring, look inside the band. On chains and bracelets, check the clasp. On earrings, check the post or the back. Common stamps include 10k, 14k, 18k, 22k, 24k, 417, 585, 750, 916, or 999. The numbers are decimal equivalents. For example, 585 means roughly 58.5% gold, which is close to 14k. If you cannot find a stamp, we test the piece in store.

No stamp? No problem. We test every piece regardless of whether it has a visible karat stamp. If a piece is unstamped, worn, inherited, or hard to read, we use in-store testing to help determine purity before calculating an offer.

Weight — Troy Ounces and Grams

Gold prices are commonly quoted in troy ounces, but jewelry is usually weighed in grams because individual pieces are small. One troy ounce equals about 31.1 grams. At Larsen's, we weigh items in front of you so you can see the reading before any calculation is explained.

How the Gold Value Math Works

Once the karat and weight are known, the basic metal-value math is straightforward. Here is the simplified version:

Gold Value Formula
Weight
in grams
×
Gold Purity
karat %
×
Market Reference Price
per gram
=
Estimated Metal Value
This gives an estimated metal value before buyer margins, refining costs, condition, item type, resale demand, and market movement are considered. At Larsen's, we explain the calculation before you decide whether to sell.

A Real-World Example

Say you have a 14k gold ring that weighs 5 grams. The math starts by figuring out how much pure gold is actually in the ring.

Example — 14k Gold Ring, 5 Grams

Weight 5 grams
Karat purity: 14k = about 58.3% × 0.583
Approximate pure gold content 2.915 grams of pure gold
Market reference price per gram Changes daily
Estimated metal value Explained in store before you decide

We do not publish a fixed example price here because the gold market changes daily, and showing an outdated number can mislead readers. What we can tell you is that we use current market pricing as a reference, then explain how purity, weight, condition, item type, and the item itself affect the final offer.

Want a ballpark before you come in? You can look up current gold market references online through sources like World Gold Council gold price data or Kitco's live gold chart, but remember that the public market price is a reference point, not a guaranteed payout. A local offer also has to account for testing, handling, resale or refining, condition, and market movement.

Melt Value vs. Payout vs. Resale Value

These terms often get mixed together. Understanding the difference helps you know why two gold pieces with the same gram weight can receive different offers.

Gold value terms customers should understand
Term What It Means Why It Matters
Melt Value The estimated value of the pure gold content based on karat, weight, and market price. This is the starting point for scrap gold, broken chains, single earrings, and many ordinary pieces.
Offer / Payout The amount a local buyer offers after testing, weighing, and accounting for costs and resale or refining risk. This is the real number you can accept or decline in store.
Resale Value The value of a wearable, signed, collectible, antique, designer, or regional piece as jewelry instead of scrap. Some Black Hills Gold, signed jewelry, coins, or estate pieces may be reviewed above ordinary melt value.

How Much Can I Get for Scrap Gold?

“Scrap gold” is the industry term for gold jewelry, fragments, and mixed pieces that are evaluated primarily for their metal content rather than for their design, brand, or resale demand. This is one of the most common gold-selling scenarios, and it is worth understanding the category on its own.

What Counts as Scrap Gold?

Common scrap gold examples include:

  • Broken gold chains — bent, kinked, or unusable
  • Single earrings — where the matching earring was lost
  • Damaged rings — cracked shanks, missing stones, bent settings
  • Class rings and school rings — usually 10k or 14k, high metal content
  • Old wedding bands — inherited or no longer worn
  • Dental gold — old crowns, bridges, or fillings from dental work
  • Miscellaneous “junk drawer” gold — mixed pieces of unclear origin, no matching set

How Is Scrap Gold Evaluated?

Scrap gold is evaluated the same way as any other gold: karat is tested, weight is measured in grams, and the total is calculated using the formula shown earlier on this page. The main difference is that scrap pieces are not reviewed for resale value beyond metal — the offer is based purely on gold content, current market conditions, and the buyer’s refining or handling costs.

For real per-gram payout ranges by karat — 10k, 14k, 18k, 22k, and 24k — see our companion payout guide, How Much Does a Pawn Shop Pay for Gold?. It shows what scrap gold typically pays at current market prices and explains the math behind each karat.

Do not throw away broken gold. Even a single broken chain, a bent ring, or a dented earring can carry real metal value based on karat and gram weight. When in doubt, bring it in for a free test — no obligation to sell.

What Not to Do with Scrap Gold

  • Do not clean or polish scrap pieces. Cleaning does not raise metal value and can waste your time.
  • Do not attempt to remove stones yourself. Many stones have little value on their own, and prying them out can damage the piece and reduce even the scrap offer.
  • Do not sort by karat before bringing pieces in. We test every piece regardless of the stamp — sorting at home wastes your time and can miss unmarked pieces.
  • Do not weigh at home on a kitchen scale. Kitchen scales use avoirdupois ounces, not troy ounces, and undercount gold weight by roughly 10%.
  • Do not sell scrap gold to the first buyer you see. A second opinion from a store that tests in front of you is worth the 15-minute drive.

When Scrap Might Not Be the Right Category

Some pieces that look like scrap at first glance may actually have resale value beyond metal content. Before you commit to selling as scrap, consider:

  • Is the piece signed by a recognized maker (Tiffany, Cartier, Landstrom’s, F.L. Thorpe, Coleman, Stamper, etc.)?
  • Is the piece vintage, antique, or Art Deco?
  • Is the piece part of a matching set that might be worth more together than separated?
  • Does the piece have documented provenance, an appraisal, or original packaging?
  • Is the piece Black Hills Gold with intact maker marks?

When in doubt, bring the piece in as-is. We will help separate ordinary scrap from pieces that deserve a closer look before anything is treated like plain melt gold.

Have a mixed box or estate to sort through? Do not try to divide it up at home. We routinely sort mixed lots into scrap, wearable jewelry, sterling silver, Black Hills Gold, coins, and costume — free, in front of you, with no obligation to sell any of it.

What Else Affects a Gold Offer?

Market pricing and purity get you to the starting point, but several other factors can affect the final offer, especially for certain types of gold items.

Broken and Scrap Gold

Broken jewelry is one of the most misunderstood categories. A broken gold chain, a bent ring, a clasp that no longer works, or a single earring can still have metal value. Gold does not lose its metal content just because the piece is damaged. If you have broken gold sitting in a drawer, text us a photo before you make the drive. For the full scrap-gold breakdown, see the section How Much Can I Get for Scrap Gold? above.

Dental Gold

Old dental crowns, bridges, and fillings can contain valuable metal and are worth evaluating. Dental gold can contain a mix of metals, so testing matters. Bring it in and we can test and weigh it the same way we evaluate other precious-metal items.

Unmarked or Unknown Gold

If a piece has no visible karat stamp, or if you are not sure whether something is actually gold, we can test it in store. We do not rely on guessing from appearance alone.

Black Hills Gold, Designer, Vintage, and Collector Pieces

In some cases, a piece may have value above its metal content. Examples may include signed designer jewelry, certain vintage pieces, collectible coins, Black Hills Gold with intact maker marks, or items with documented provenance. These cases are less common with everyday jewelry, but they are worth mentioning if you believe the piece may have resale or collector value beyond its gold content.

Melt value and resale value are not always the same. A common broken chain may be reviewed mostly by metal content, while a signed designer piece, collectible coin, antique item, or desirable Black Hills Gold piece may need a closer look before it is treated like ordinary scrap gold.

Gold-Plated, Gold-Filled, and Solid Gold Are Different

Not every gold-colored piece has the same kind of gold content. This is one of the most common surprises when customers bring in older jewelry, estate boxes, watches, chains, or mixed pieces.

  • Solid gold — usually stamped 10k, 14k, 18k, 417, 585, or 750. These pieces are evaluated by karat, weight, testing, condition, and the item itself.
  • Gold-filled — has a layer of gold bonded to another metal, but it is not valued the same way as solid gold jewelry.
  • Gold-plated — has a thin surface layer of gold over base metal and often has little precious-metal value by itself.
  • Costume jewelry — may still be worth checking if it is signed, vintage, or part of a larger estate group, but most pieces are not valued like gold.
Unsure what category your piece falls into? Bring it in as-is. We can test and separate likely solid gold, gold-filled, gold-plated, sterling silver, and costume pieces so you understand what is in the group before deciding what to do.

What About Gold Coins and Bullion?

Gold coins and bullion can be different from ordinary jewelry because recognized bullion products may trade with a premium above melt value. American Gold Eagles, other recognized bullion coins, bars, and older collectible coins should be reviewed separately from scrap jewelry. Do not clean or polish coins before bringing them in.

For official context on U.S. bullion products, see the United States Mint bullion program reference.

What About Silver?

The same basic logic applies to silver: purity, weight, item type, condition, and current market conditions all matter. Common silver items include sterling silver jewelry stamped .925, silver flatware, silver rounds, silver bars, and pre-1965 U.S. silver coins.

See our Silver Bullion & Coins page for full details, or read the silver bullion guide for more context on spot price, rounds, bars, coins, and sterling markings.

What to Bring for a Gold Evaluation

Do not clean, polish, remove stones, or separate sets before bringing jewelry in. Older rings, estate pieces, Black Hills Gold, signed jewelry, and matching sets may need to be reviewed as they are. Cleaning or altering a piece first can remove useful clues or affect collector and resale context.
  • The pieces themselves — gold or silver jewelry, coins, bullion, or broken pieces you want evaluated.
  • Valid government-issued photo ID — useful and often needed for selling precious metals or completing certain in-store transactions.
  • Estate paperwork, boxes, or appraisals — helpful context when available, but not required for most evaluations.
  • Visible karat or quality marks — such as 10k, 14k, 18k, .925, 417, 585, 750, 916, or 999.
  • Estate or inherited pieces — bring everything and let us sort through it with you.
  • Dental gold if you have it — old crowns and bridges are easy to overlook but may still be valuable.

Gold Value FAQ

How much is my gold worth in Mobridge, SD?

Gold value depends on karat, weight, current market pricing, condition, testing results, and the item itself. Larsen's tests and weighs items in store and explains the offer before you decide.

How much can I get for scrap gold?

Scrap gold offers are based on karat, gram weight, and current market pricing. Common scrap items — broken chains, single earrings, class rings, damaged rings, wedding bands, and dental gold — are all evaluated the same way: we test purity, weigh in grams, and calculate against current market pricing. For per-gram payout ranges by karat (10k, 14k, 18k, 22k, 24k), see our companion guide, How Much Does a Pawn Shop Pay for Gold?.

Is broken jewelry evaluated the same as wearable gold?

Broken gold is evaluated primarily for its metal content. Wearable and intact jewelry can also be considered for resale value depending on the piece. If a broken piece has a recognizable maker's mark, is signed by a known designer, or is antique, it may be worth reviewing separately before being treated as ordinary scrap.

What does karat mean when selling gold?

Karat describes gold purity. For example, 24k is pure gold, 22k is about 91.6% gold, 18k is about 75% gold, 14k is about 58.3% gold, and 10k is about 41.7% gold.

Does broken gold still have value?

Yes. Broken chains, damaged rings, single earrings, old class rings, and other damaged gold pieces can still have value because of their metal content.

Do you pay spot price for gold?

No. Spot price is a market reference point, not the final payout. Offers also account for purity, weight, testing, condition, handling, resale or refining costs, and market movement.

Can I text photos before selling gold?

Yes. Use the Contact page to send clear photos before driving in. Final offers are confirmed in store after testing, weighing, and inspection.

Is gold-plated jewelry worth anything?

Gold-plated jewelry usually has only a thin surface layer of gold and often has little precious-metal value by itself. Bring it in if you are unsure, especially if it is part of an estate group, signed piece, watch, or mixed jewelry box.

Should I clean gold before bringing it in?

Usually no. For scrap gold, cleaning is unnecessary. For Black Hills Gold, designer jewelry, old coins, signed pieces, or estate pieces, cleaning or polishing can remove clues or affect resale context. Bring items in as-is.

Can gold be worth more than melt value?

Yes. Certain signed pieces, Black Hills Gold, collectible coins, designer jewelry, antique pieces, or items with strong resale demand can be reviewed beyond basic melt value.
