Gold, silver, platinum, palladium — as goods

Gold and silver were money in the sense this classroom already taught: a unit defined as a weight, a mint, a swap window. That is a policy history. It is not a reason last on a bar cannot fall.

Platinum sat in a short money experiment: the Russian Empire coined 3-, 6-, and 12-ruble platinum pieces from 1828 to 1845, then stopped. The usual telling: the metal’s last was jumpy, coins were melted, and the shop gave up. A brief coinage is a record. It is not “platinum is money” as a personality.

Palladium was isolated in 1803 (William Hyde Wollaston in the usual telling). It was never a unit of account at a mint. Auto catalysts, electronics, and dentistry sit in its demand story. A catalyst is a use. A use is not a currency.

People bundle gold, silver, platinum, and palladium as “precious metals” because they are dense, shiny, and trade in troy ounces. Rhodium often rides in the same headline. A bundle is a headline. Gold’s money story, silver’s money story, platinum’s short coinage, palladium’s industrial book, and rhodium’s never-a-unit book are five doors. Mixing them is how a pitch sells a “stack” as if 1870 applied to all of them.
