One Ounce of Platinum, Refiner Our Choice
This listing is one troy ounce of .9995 fine platinum in an assay card, with the refiner chosen from the stock we have on hand. It is for buyers who want the metal and are happy to let the brand vary.
Platinum, the Little Silver
The name comes from the Spanish platina, a diminutive of plata, silver, after the metal’s silvery white color. Antonio de Ulloa’s 1748 report on a new metal from Colombia was what began to bring it to scientists’ attention. Today South Africa leads production of the platinum group metals. Platinum is a key part of catalytic converters, and it also goes into jewelry, laboratory equipment and electrical contacts.
Secondary-Market Bars, Listed as Used
These bars come to us from the secondary market, so we list the condition as used. Every bar ships in an assay card, as the listing title says. Because the bars have changed hands before, we cannot promise every card is untouched or every bar looks fresh from the refiner, but the platinum is unchanged and the card states what the bar holds.
The refiner is not something you can request. The design, the card style and whether the bar carries a serial number all depend on which bar fills your order.
Smaller Than Gold, Ounce for Ounce
Platinum is denser than gold, about 21.45 grams per cubic centimeter against gold’s 19.28. The same troy ounce takes up roughly a tenth less space, so a 1 oz platinum bar is slightly smaller than gold of the same weight.

1 oz Platinum Bar in Assay Card FAQ
Which refiner will I receive?
Whichever refiner’s bar is in stock when your order ships. Refiner requests are not accepted, and a multi-bar order may include more than one refiner.
Why is the condition listed as used?
These bars come from the secondary market, meaning they have been owned before they reach us. The listing does not promise new-from-the-refiner packaging, and the assay card shows what the bar holds.
Is this platinum bar IRA eligible?
Our Specifications tab lists it as IRA eligible. Federal rules allow platinum bullion in an IRA at .9995 fine or better, held by the IRA’s trustee rather than at home. Custodians set their own lists of accepted products, so confirm with yours before you buy.
Why are no dimensions listed?
Because the refiner varies, so does the size and shape of the bar. Every bar weighs one troy ounce, but the dimensions vary from one refiner to the next.
Does the bar have a serial number?
That depends on the refiner, so we cannot promise one on every bar. If your bar carries one, it should match the number on the card.
