One-Ounce Platinum Bars
Ten-ounce and 1-oz platinum bars are convenient ways to invest in platinum because they carry the smallest premiums of the platinum investment products available, and they are easy to secure. As are platinum coins, platinum bars are .9995 fine (99.95% pure).
Several major refineries turn out platinum bars. Platinum coins that are minted by government mints carry legal tender values and sell at higher premiums than platinum bars. 1-oz Platinum Maple Leafs and 1-oz American Platinum Eagles are the most readily available platinum coins.
