If you don't already have some, a dozen silver coins is a great thing to have. Gold is pricier, and just for your consideration: it costs almost $1000/oz in a developed country to mine, refine, and mint a gold coin.
Hell, splurge on a case of 22longs, they will never lose their value. just don't buy plastic. There are enough posts here explaining why our money will be worthless one day, let alone that useless "thing" advertised as a must-have.

Silver is not a rare earth metal
WhyNoDonuts ago
How would one go about amassing rare earth metals, and once obtained, who would buy them and at what established prices? I was only suggesting silver because gold coins are really expensive. Besides, a mix of metals is best - but don't leave them in safety deposit boxes!

http://www.australianminesatlas.gov.au/education/fact_sheets/silver.html The earth makes silver naturally. Gold, Platinum and Palladium all come from space. I have invested in BTC which seems to be easier to use. Also im not one for buying jewelry but i prefer buying Tanzanite for my wife when i do. It can only be found in one location in the world.
