The Best Place to Sell Estate Platinum in Los Angeles
When you need to sell estate platinum in Los Angeles, South Bay Coin is the licensed, bonded, and insured precious metals dealer that families across the South Bay have trusted since 1980. Estate and inherited platinum often arrives as antique rings, Art Deco brooches, and diamond mountings that demand an experienced eye, and our on-site appraisers have valued thousands of these pieces.
Unlike pawn shops and jewelry stores that resell estate platinum to a refiner at a markup, South Bay Coin operates its own refinery. Because we process the metal ourselves, we eliminate the middleman and pay you a higher percentage of the live platinum spot price. Many buyers in Los Angeles cannot reliably tell platinum from white gold or palladium, and that single mistake can cost a seller hundreds of dollars on one piece. We test every item in front of you and confirm the exact metal before we make an offer.
We also recognize when an estate piece is worth more than its melt value. An Edwardian filigree ring or a signed mounting can carry collector value a scrap buyer would overlook. Whether you are settling an estate, downsizing, or simply ready to sell platinum jewelry you no longer wear, you receive the same transparent appraisal and the highest possible offer. Bring your gold, silver, estate diamond jewelry, and platinum together in one visit, and we will appraise everything at no charge.

Live Precious Metal Spot Prices
Updated every 60 seconds during market hoursHow We Value Estate and Antique Platinum
Estate platinum is valued on two layers: the metal content and, when applicable, the collector value of the piece itself. We begin with the hallmark. Genuine platinum is stamped PT950, 950, 900 PT, or simply PLAT, where 950 means the piece is 95 percent pure platinum. That purity is far higher than gold jewelry, where 14K is only 58.3 percent gold, so platinum frequently holds more precious metal than its size suggests.
Because platinum is one of the densest metals at 21.45 grams per cubic centimeter, it feels noticeably heavier than white gold or silver of the same size. We confirm authenticity with acid testing and electronic verification, then weigh each piece in troy ounces and calculate the metal value against the live spot price. Stones are evaluated separately, so a platinum mounting set with old European or rose-cut diamonds is appraised for both the metal and the diamonds.
Antique platinum deserves special attention. Platinum became the signature metal of the Edwardian era from 1901 to 1910 and the Art Deco period of the 1920s and 1930s, prized for the lace-like filigree and milgrain detailing that gold could not achieve. Authentic pieces from these eras, along with designer pieces from Cartier, Tiffany, and Van Cleef & Arpels, can command well above melt value among collectors. If you are unsure whether your item is platinum or simply old white gold, bring it in and we will tell you exactly what you have.

What Our Customers Say
Common Questions About Selling Estate Platinum
The value of estate platinum depends on its purity, its weight in troy ounces, and the live platinum spot price. Most platinum jewelry is 95 percent pure, far higher than gold. Antique and signed pieces may also carry collector value. We test and weigh everything in front of you before making an offer.
South Bay Coin in Lawndale buys inherited platinum jewelry from sellers across Los Angeles County, including Torrance, Redondo Beach, and Manhattan Beach. We are a licensed refinery, so we pay more than pawn shops or jewelry stores. Walk in with no appointment for a free appraisal and same-day cash.
Platinum is far denser than white gold, so it feels noticeably heavier for its size. It is also naturally white and does not need rhodium plating. We confirm the metal with hallmark inspection, acid testing, and electronic verification, because many buyers mistake platinum for white gold or palladium and underpay.
Genuine platinum is usually stamped PT950, 950, 900 PT, or PLAT, with 950 meaning 95 percent pure platinum. In the United States, items marked PLAT or PT without a number must be at least 95 percent pure. Antique pieces sometimes lost their marks, so we test rather than rely on the stamp alone.
Yes. Platinum defined the Edwardian era from 1901 to 1910 and the Art Deco period of the 1920s and 1930s, known for filigree and milgrain detailing. We recognize authentic pieces from these eras and pay collector value when a piece warrants it, not just the metal melt price.
Often, yes. An authentic Edwardian filigree ring, an Art Deco brooch, or a signed mounting from Cartier or Tiffany can be worth far more to a collector than its metal content alone. We evaluate craftsmanship, era, and maker before defaulting to melt value, so you are never shortchanged on a rare estate piece.
We appraise the platinum and the diamonds separately. The metal is weighed and valued against spot price, while the stones are graded on cut, color, clarity, and carat. Old European and rose-cut diamonds common in estate pieces are valued for their antique character, so you receive full value for both components.
No appointment is needed. Walk into our Lawndale showroom at 16916 Hawthorne Blvd during business hours and an appraiser will help you right away. If you prefer, call (310) 363-7808 or text photos to (310) 363-2697 for an estimate before you visit.
Yes. We regularly help families settling an estate sell platinum jewelry, diamond pieces, coins, and bullion. Bring any estate paperwork and a valid photo ID. We appraise each item transparently, explain every offer, and pay the same day, with no pressure to sell anything you would rather keep.
A pawn shop typically resells your platinum to a refiner and pays a low percentage of spot, and many cannot recognize an antique piece worth more than melt. South Bay Coin is the refinery, so we pay a higher percentage and reward collector value on estate and signed pieces.
