What is the value of a 2000 US 1 dollar coin?
If you have a silver piece with 1 OZ on the back it's a bullion
coin worth about $18 (as of 07/2008) for its metal content.
If you have a gold-colored Sacagawea dollar it's made of brass
and there are about a billion of them in circulation so they're not
likely to EVER be worth more than $1.00
