We buy platinum in Miami at live PGM spot pricing. Platinum bullion bars, sovereign platinum coins, 950 and 900 platinum jewelry, platinum-cased watches, and platinum scrap. On-site XRF testing in our Surfside showroom at 9573 Harding Avenue. Same-day cash for transactions under $25,000, same-week wire for larger amounts.
Platinum is the third leg of the precious metals stool, less common at street-level cash-for-metal shops because pricing requires real PGM market awareness. CJ William prices off live platinum spot at the moment of the transaction, with the spread quoted up front: typically 92 to 95 percent of spot on investment bullion, 80 to 88 percent on jewelry, and refiner rates on scrap. No mystery price.

Frequently Asked Questions
What platinum does CJ William buy in Miami?
Platinum bullion bars and rounds from recognized refiners (PAMP, Valcambi, Credit Suisse, Johnson Matthey, Engelhard), platinum coins (American Platinum Eagle, Canadian Maple Leaf, Australian Koala, Isle of Man Noble), platinum jewelry, platinum-cased watches, and platinum scrap including catalytic-converter platinum from automotive recycling.
How is your platinum offer calculated?
For investment-grade platinum bullion we typically pay 92 to 95 percent of spot. For platinum coins we typically pay 88 to 93 percent of spot. For platinum jewelry (950 platinum, 900 platinum) we typically pay 80 to 88 percent of melt value after purity testing. For scrap and catalytic platinum we pay refiner rates less a handling margin. Spread is wider than gold because platinum is less liquid and refining costs are higher.
Why is platinum priced differently than gold or silver?
Platinum trades at a different ratio to gold than it used to (historically platinum was priced above gold, now often below). It is also less liquid in the dealer market, so spreads are wider. We base every offer on live PGM spot at the moment of the transaction so you see the math, not a mystery price.
Do you buy platinum watches?
Yes. Solid platinum-cased watches from Patek Philippe, Vacheron Constantin, A. Lange & Sohne, Audemars Piguet, and platinum Rolex references are valued at the higher of the watch market value or the platinum melt value. See Sell Your Rolex in Miami for the full Rolex process.
Do you require ID to sell platinum in Florida?
Yes. Florida law requires precious metals dealers to verify the seller’s identity and record the transaction. Please bring a government-issued ID.
Do you report sales to the IRS?
Cash transactions exceeding the IRS Form 8300 threshold ($10,000 in a single transaction or related transactions) require federal reporting by the buyer. Wire payments above the threshold do not trigger Form 8300. We provide a bill of sale and payment confirmation for your CPA in every transaction.
How do you test platinum purity?
On-site XRF spectrometry, non-destructive, accurate to within 0.5 percent. Hallmarks (PLAT, PT950, 950 PT) verified visually and confirmed on XRF. For unusual or heavily worked pieces we may also use acid testing on an inconspicuous area, with the seller’s consent.
Can I sell platinum remotely?
Yes. Send clear photos including any hallmarks for an initial estimate, then ship via fully insured FedEx overnight using a label we provide for transactions over $5,000. Payment wired the same day we receive and verify.
