Banks do not use bullion(gold or silver) anymore. Most nations now have a fiat currency that is backed by nothing more than a “promise to pay” from the central bank.Where can you buy gold coins?
You can buy gold coins in a number of ways. Online sites like eBay are popular choices and occasionally you can get a good deal. However, it is usually simpler and cheaper to buy gold coins from an established jewelry or coin dealer, or directly from a producing mint such as the U.S. Mint.
