How Gold Is Valued by a Los Angeles Gold Buyer
Before you sell, learn exactly how gold is valued: how a professional gold buyer in Los Angeles measures purity, weighs net metal, and applies the live market. At South Bay Coin every test and every number happens in front of you.
How Gold Is Valued in Los Angeles Before You Sell
How gold is valued comes down to three measurable facts about the object in your hand: how pure the metal is, how much of it you actually own once everything that is not gold has been set aside, and what that metal trades for on the open market the day you sell. Nothing else in the transaction is a mystery, and none of it should be taken on faith.
South Bay Coin has walked clients across Los Angeles County through that arithmetic since 1980. We are a licensed, bonded, and insured precious metals dealer in Lawndale, and we test, sort, and weigh every piece where you can see it happen, then say out loud how each figure was reached. Because we operate an in-house refinery instead of passing your metal to a third party, the offer reflects true metal content rather than a middleman's margin. That is the single biggest reason our numbers tend to land above pawn shops and jewelry store counters.
This page is written for the person who wants the process explained before they commit to anything. Whether you plan to sell gold in Los Angeles today, want to know what your gold and silver coins are really worth, or are weighing an offer on sterling silver against an honest second opinion, the steps below are the same ones we run at the counter. Every appraisal is free, there is never an obligation to sell, and the more you understand the method, the better you can judge any offer you receive anywhere in the South Bay.

How Is Gold Purity Tested and Measured in Karats?
Purity is the first of the three facts, and in the United States it is written in karats. Pure gold is 24 karat. An 18K piece is 75 percent gold, 14K is roughly 58.3 percent, and 10K is about 41.7 percent, with the remainder made up of copper, silver, nickel or zinc added for hardness and color. Only the gold fraction carries metal value, so settling purity correctly decides everything downstream.
We begin with the hallmark, reading whatever is stamped inside a band or on a clasp, and then we confirm it rather than trusting it. Most jewelry is read with a non-destructive XRF analyzer, which reports the full alloy in seconds without scratching the piece, and we confirm with a touchstone or a controlled acid test when a reading deserves a second opinion. Stamps are a claim, not proof: they wear away, they are applied abroad under different conventions, and on plated goods they describe a layer rather than the body underneath.
This is also where an honest valuation separates itself from a lazy one. The common shortcut is to pile mixed jewelry together and pay the whole heap at the lowest karat present, or to quietly run plated pieces across the scale with the solid ones. We sort your items into karat groups, set aside anything plated, filled or vermeil, and price each group on its own reading. Knowing how purity is established protects you at any counter in the South Bay, including ours.
How Much Is My Gold Worth per Gram or Troy Ounce?
Once purity is settled, weight decides how much pure gold you actually own, and precious metals are not weighed the way groceries are. The trade uses the troy ounce, about 31.1 grams and roughly a tenth heavier than the ounce most people picture. Many counters also work in pennyweights, where one pennyweight is about 1.555 grams and twenty pennyweights make a troy ounce. Grams, pennyweights and troy ounces all describe the same metal, just cut into different units.
That is exactly where sellers lose money without noticing. The oldest trick in the category is to weigh in pennyweights and quote a rate that was written for grams, which shrinks the number by a factor the seller never sees. Ask any buyer to name the unit and the rate in the same sentence. We weigh on a calibrated scale that reads to three decimal places, turn it toward you, and deduct stones, spring bars, steel clasps and enamel to reach a true net metal weight. Gemstones are assessed on their own terms and never counted as gold.
The third fact is the market. Gold trades globally and the price moves all day, so any valuation is a snapshot rather than a standing quote, and that market rate is the baseline every honest offer starts from. We apply the current rate to your verified purity and your net weight, then walk through the result out loud. Coins and bullion get a second look, because collector demand can carry a piece well past its melt value, and we never pay melt for something rare.
Gold and Silver We Value and Buy for Cash
We value gold and silver in any condition, any karat, and any form. Every item is tested, weighed, and assessed for both its metal content and any collector value it carries.
Sell Gold Jewelry
Chains, rings, bracelets, earrings, and pendants. We group by karat and deduct stones so the offer covers gold only.
Sell Gold Coins and Bullion
Eagles, Krugerrands, Maple Leafs, bars, and ingots. We weigh melt content and check whether a collector premium applies.
Sell Scrap and Dental Gold
Broken pieces, single earrings, dental crowns, and bridges. Condition changes nothing, because value follows verified metal.
Sell Silver Coins, Bars and Flatware
Sterling at 925, coin silver, rounds, bars, and flatware. We confirm fineness first, then value net weight against the silver market.

What Our Gold Valuation Customers Say
Common Questions About How Gold Is Valued
How is gold valued when you sell it?
Gold is valued on three things: purity, net weight, and the live market. We confirm the karat to find how much of the item is actually gold, weigh what remains once stones and non-gold parts are deducted, then apply the current market rate. Every figure is explained in front of you before any offer is made.
How do gold buyers test gold purity?
A careful buyer verifies purity instead of trusting the stamp. We read the hallmark first, then confirm it with a non-destructive XRF analyzer that reports the whole alloy in seconds, and add a touchstone or controlled acid test when a reading needs a second opinion. Fire assay is destructive, so it stays at the refinery.
What is the difference between karat and weight when valuing gold?
Karat measures purity, the share of the item that is gold, so 24K is pure and 14K is about 58.3 percent. Weight measures how much metal there is in total. Value needs both, because pure gold content is purity multiplied by net weight. A heavy 10K piece can hold less gold than a lighter 18K one.
Why is gold weighed in troy ounces and pennyweights instead of grams?
Precious metals use the troy system. A troy ounce is about 31.1 grams, roughly a tenth heavier than a kitchen ounce, and one pennyweight is about 1.555 grams, with twenty pennyweights to the troy ounce. The metal is identical, only the unit changes. Always confirm that the unit and the quoted rate match.
Does XRF testing damage my gold?
No. XRF, or X-ray fluorescence, is non-destructive. It reads the metal composition without scratching, cutting or melting anything, which suits jewelry, coins and high-value pieces. It also flags gold-plated items that carry only a thin surface layer, so plated goods are never valued as though they were solid gold.
How is scrap gold valued compared to intact gold jewelry?
Identically, whenever the value sits in the metal. Condition is irrelevant to purity and weight, so a broken chain, a tangled knot or a single earring is valued exactly like a wearable piece of the same karat. A signed or designer item can carry demand beyond its gold, and we check for that before pricing it as scrap.
What is the difference between melt value and numismatic value?
Melt value is what the raw metal is worth given purity, weight and the market. Numismatic value is the collector premium some coins carry for rarity, date, mint or condition. A coin can be worth far more than its metal, which is why both numbers get checked and why melt is never assumed on a collectible.
How do you value gold coins and bullion?
For bullion such as Eagles, Krugerrands and bars, we verify weight and fineness and value the metal against the live market. For collectible coins we also weigh date, mint, condition and rarity to capture any premium. Each coin is examined closely, edge included, because a premium can far exceed the metal alone.
Why do two gold buyers value the same item differently?
Usually the difference is in the process, not the gold. One buyer lumps mixed karats together, weighs in one unit but quotes in another, or treats plated pieces as solid. A buyer with an in-house refinery values true metal content directly rather than discounting to leave room for a middleman further down the chain.
