To give the currency a value, we need to know the following: what it is - one dollar bill, where it was printed for what reserve bank, when it was printed - sometime after 1957, its condition - don't know, and its serial number - don't know. Without this information, I can say that the bill is worth at least a dollar and if other conditions are known - uncirculated instead of circulated, star in the serial number instead of none, etc. it could be worth more.
