Acceptability: Of all the commodities you can think of, no other commodity comes even close to the acceptance and liquidity of precious metals (PM). Worldwide, you can walk around any city, anywhere in the world, and you’ll find a store where you can sell gold and silver. You lose some money on premiums and commissions (shop around) but you can convert your precious metals to whatever currency is in use.
Stability: No other commodity even comes close. Throughout history men have considered gold and silver valuable and always will. The market can be tampered some as seen recently, but there will always be a limit. Unlike fiat currencies, you cant “make” real gold and silver just by punching 0000s into a computer. In spite of recent ups and downs, gold and silver have always retained a somewhat similar purchasing power. A denarius silver coin was the daily minimum wage, considered by historians as “20 USD in bread”, brought to today’s prices. This was the minimum wage and a skilled worked could easily earn five times as much.

Portability: Cans of food, jerry cans of gas, tools, ammo, medicines, matches, booze and cigs. All sounds good for a post-end of the world Barter Town. As explained above, you don’t need to wait for the end of the world for gold to be accepted, it is as of right now just like it was 1000 years ago and will be for the next 1000 years to come. But precious metals, particularly gold, has another advantage: portability and compactness. If the worst happens, you can drop a few coins in your pocket, and that’s enough wealth to start over elsewhere. Try doing that with 10000 cans of soup or 50.000 rounds of 22LR. Keep in mind here, silver may be “cheap” and its good for saving little by little, but weight adds up fast with silver!
Uniformity: Being pure metals, there’s no different components involved and with simple tests (acid, electric) the purity can be confirmed even in junk precious metals.

Durability: Unlike tools, food and other supplies, gold and silver doesn’t rust, age or otherwise go bad. You can still dig up a 5000 year old coin and its still as valuable as it was when first minted (ok, its even more valuable in that case!) The point is, PMs don’t go to waste and it doesn’t get replaced by some other fiat currency bill. What you put aside today for a rainy day can be used tomorrow or by your grandchildren in 50 years. Of course, should there’s be an economic collapse it would be just a as valuable and then some.
