1955 Penny

Sometimes a penny is worth more than a penny. If you think you're seeing double, save that coin. A 1955 penny has a "double-die date." In uncirculated condition -- not a blemish on it -- it's worth about $27,000. Even in less than perfect condition it'll fatten your bank account to the tune of $570.

So a 1957 Penny couldn't be worth much less than that.
