Platinum coins are minted by sovereign governments with guaranteed purity of .9995 fine platinum and legal tender status. They carry higher premiums per ounce than platinum bars but offer stronger resale liquidity and wider dealer recognition. FindBullionPrices compares platinum coin prices from online dealers. Sort by premium to find the lowest-cost platinum coins.

Sovereign mints build costs into the premium: die production, design licensing, legal tender certification, and lower production runs compared to bars. A 1 oz American Platinum Eagle typically carries a 5-8% premium over spot, compared to 3-5% for a 1 oz platinum bar from PAMP or Valcambi. The tradeoff is liquidity — dealers recognize and buy back sovereign coins at tighter spreads.
Random-year and secondary-market platinum coins — previously owned pieces resold by dealers — often trade at lower premiums than newly minted issues. The platinum content is identical. For buyers focused on cost per ounce, secondary-market Platinum Eagles, Britannias, and Maple Leafs are worth checking. Use the product grid above to compare — secondary-market products show up alongside current-year issues.
