Rare Coin

how do you find how much a rare coin is worth?

well, i have these two $1 coins and i dont know how much they are worth!!!!
one of them is a 1825-1829 John Quincy Adams coin and the other is a 1789-1797 George Washinton coin
can anyone help me??!!!

Those aren't Rare Coins. They're new coins, from the current Presidential Dollars series. Washington is 2007 and JQ Adams is 2008. They're worth face value.

To answer your question, you find out how much a coin is worth by, in order:

1. Identifying exactly what you have.
2. Accurately grading the coin.
3. Looking at sales results of similar coins.
