It's only worth a dollar so feel free to spend it.

The only US coin that has the dual-dates of 1797-1801 on the obverse is a 2007 John Adams Presidential dollar, the date and mintmark is on the edge of the coin. If you got the coin from a bank or change, it's face value. Only a proof or mint state coin will have a premium.

Its value would depend upon which coin it was and its condition.
