A copper standard is a monetary system in which the standard economic unit of account is based on a fixed quantity of copper. The copper standard was inspired by the gold standard and it is the basis of the monetary system of some micronations which hold substantial copper reserves.
Historically, the gold standard, silver standard and bimetallism have been dominant among internationally recognized states. As for micronations, given its geographic, infrastructural, population and financial limitations, cheaper metals or commodities had to be used to back currencies with non-symbolic commercial value. The copper standard was famously first introduced by the Grand Republic of Delvera, and later adapted by the North American Confederation and the Kingdom of Ebenthal, while it is also being incorporated by Karnia-Ruthenia who absorbed Delvera and the NAC's successor state, the Occidian Empire.
