South Bay Coin buys 10K gold jewelry, class rings, chains, and broken pieces across Los Angeles County. Free testing at the counter, no appointment needed, and an offer explained piece by piece before you decide anything.
The best place to sell 10K gold in Los Angeles
Most people who come in to sell 10K gold start by apologizing for it. Ten karat is the palest and the hardest gold in the drawer, and somewhere along the way it picked up a reputation as the karat not worth carrying anywhere. That reputation is wrong. Ten karat is solid gold all the way through, 41.7 percent pure by weight, and it is bought on exactly the same arithmetic as any other karat: what the piece weighs, what it tests at, and where the gold market sits during the hour you are standing at our counter.
South Bay Coin is a licensed, bonded, and insured precious metals dealer at 16916 Hawthorne Blvd in Lawndale, buying gold across Los Angeles County since 1980. We operate our own refinery, so a 10K chain sold here does not pass through a middle buyer on its way back to being metal. Removing that layer is why a walk-in offer at our counter routinely beats what the same handful of rings brings a few blocks up Hawthorne Blvd.
Nothing here carries a minimum. One class ring is a transaction. So is a coffee can of tangled chain, single earrings, broken clasps, and charms nobody claimed. We sort a mixed lot by karat in front of you rather than paying the lowest karat in the pile across the entire weight, which is the most common way a mixed bag quietly loses money. If the same bag holds gold jewelry in heavier karats, a signed designer or luxury jewelry piece, or something worth more intact than melted, we tell you that before we weigh anything.
Every test happens on the counter in front of you, and every appraisal is free whether you sell or not. Customers drive in from Torrance, Redondo Beach, Manhattan Beach, Hawthorne, Inglewood, and Gardena to sell gold in Los Angeles without an appointment, a shipping label, or a wait.

What a 10K gold stamp tells you, and what it does not
Ten karat has a marking problem no other karat has. Federal marking rules set 10 karat as the minimum fineness allowed for the gold layer on plated goods, so the number 10K appears on gold filled, rolled gold plate, and electroplated jewelry more often than any other karat number in the case. That is why a stamp reading 10K is not the end of the question. The characters around it are.
A fraction in front is the giveaway. Marks like 1/20 10K GF or 1/40 10K RGP mean the 10 karat gold is a layer bonded over a base metal, and the fraction states how little of the total weight that layer accounts for. Letters behind the number do the same work: GF is gold filled, RGP is rolled gold plate, GP is gold plate, and HGE is heavy gold electroplate. A solid piece carries the karat mark alone. Written as 10K, 10KT, or the millesimal fineness 417 (occasionally 416), it means 10 parts gold in 24 throughout the whole object.
The mark people misread most often is 10KP. The P stands for plumb, not plated. It was a maker declaring the alloy hit its stated purity exactly rather than rounding toward it, and it shows up mainly on American pieces from an older stamping era, which makes it a useful dating clue on estate lots. Since 2018, marketing rules no longer require 10 karat as the floor for calling something gold, so legitimate 8K and 9K stamps now circulate here too.
Stamps get tested, never taken at face value. An X-ray fluorescence reading gives us the composition without touching the piece, an acid test on the touchstone confirms it, and worn or unmarked items are tested exactly the same way. Fittings, solder joints, and clasps are checked on their own, because they are frequently a different alloy than the piece they sit on.
10K gold jewelry we buy for cash
Condition is not a factor. Ten karat gold is bought by weight and tested purity, so bent, snapped, tarnished, and unmatched pieces are all worth carrying in.
10K Rings and Wedding Bands
Wedding bands, engagement settings, signets, mens rings, cocktail rings, and stone-set pieces where the mounting is 10K gold.
Class Rings and School Jewelry
High school and college class rings, service and fraternal rings, and award pendants, the great majority of which were made in 10K gold.
10K Chains and Bracelets
Rope, curb, figaro, box, and herringbone chains, tennis and charm bracelets, plus loose charms, single earrings, and pendants.
Scrap, Dental and Unmarked Gold
Broken links, bent bands, dental crowns and bridges, and anything unstamped that may still test in the 10K range.

Common questions about selling 10K gold
South Bay Coin buys 10K gold at 16916 Hawthorne Blvd in Lawndale, minutes from Torrance, Hawthorne, and Redondo Beach. Walk in during business hours with no appointment. We test and weigh in front of you, explain the offer, and pay on the spot if you accept it.
It means gold filled, not solid gold. The 10K describes only a bonded outer layer, and the fraction states that the layer accounts for one twentieth of the total metal weight. The core underneath is base metal. Marks reading GP, RGP, or HGE work the same way and are not solid gold.
Yes. Ten karat is 10 parts pure gold in 24, which works out to 41.7 percent gold running through the entire piece rather than sitting on the surface. The remaining alloy is usually copper, silver, and zinc, which is what makes 10K harder and paler than higher karats.
Three inputs, in this order. We confirm the purity by testing rather than trusting the stamp, weigh the confirmed gold in grams or pennyweights on a certified scale, then price that pure gold content against the live market at that moment. You watch each step and we show our arithmetic.
It is the millesimal fineness mark for 10 karat gold, meaning 417 parts gold per thousand. You may also see 416 on older or imported pieces, which is the same alloy expressed slightly differently. Both indicate solid 10K throughout, and both get tested at our counter before any offer.
No, and this is the most common misreading we see. The P stands for plumb, meaning the maker guaranteed the alloy hit its stated purity exactly instead of rounding toward it. A 10KP mark is solid gold and a helpful dating clue, since it appears mostly on older American made jewelry.
Yes, and class rings are one of the most common 10K items we see. Most were manufactured in 10K gold with a synthetic stone, which carries no separate value, so the ring is valued on its gold weight. Heavy older rings often surprise people. Engraving does not reduce the offer.
Yes. Color comes from the alloy metals mixed with the gold, not from the gold content, so 10K yellow, white, and rose all contain the same amount of pure gold and are valued identically. White gold pieces are often rhodium plated on the surface, which does not change what is underneath.
Absolutely. Damage is irrelevant to gold content, so snapped chains, bent bands, and single earrings are all worth bringing. Stones are handled separately: we deduct their weight from the gold and evaluate any diamond or gemstone worth a real offer on its own merits before you decide.
You do not have to, because we sort every mixed lot by karat before weighing it. Bring the whole box exactly as it is, including unmarked pieces. Sorting matters enormously, though: a buyer who weighs mixed karats together and pays the lowest one costs you real money.
