/----/ I've heard more than one "expert" say we should tie the US dollar to a rare metal like palladium or another such rare metal. Mint four coins, put them in Fort Knox, and declare their value at 10 trillion US dollars. Use them to pay off the debt with something left over. Problem solved.
Palladium is found in similar mineral settings as other PGMs. Most palladium is used for catalytic converters, but other uses include jewelry, dentistry, and surgical instruments. Palladium is also an exchange traded metal (along with platinum, gold and silver) A palladium coin produced by the Royal Canadian Mint. Palladium is an exchange traded metal, and these coins are sought after by collectors and speculators.
