Get started in collecting coins.
Coins were created to help stabilize economies by minting metals. Coins are usually distributed by governments for the purpose of having something with a set value. But as time passes some coins has become collectable.
Collectable coins are those that are rare. Some are rare because of a flaw in the minting process, there was a limited amount made at a minting facility.
From 1932-1964 quarters were made out of silver. Now the price of silver inside that quarter is worth a lot more than a quarter. You can either put it in a coke machine or exchange it for possibly a few dollars. But if you were to find a 1932 quarter minted in Denver, you can walk away for much much more.
