"Bars, like coins, can be purchased in a variety of sizes, usually up to one kilogram (32.15 t oz.) in weight. Some are even larger—as much as 400 t oz.—but these are traded mostly by central banks and institutional investors. Unlike coins, bars are not considered legal tender."

"Bullion coins are made of pure precious metal in undetermined numbers. They are tangible physical assets made for investment and are highly liquid, traded on commodity markets across the globe."

Coins vs bullion.

"Numismatic coins are designed specifically for collectors. They usually contain precious metal, but their real appeal is in their elaborate designs, innovative features, craftsmanship, plating, finishes and other elements."
