What is a silver Ike 1 circulated coin worth?

Circulation Ike dollars were never struck in silver. Check the coin's edge - it should show a copper core just like a dime or quarter. In that case it would be worth face value to $1.25 depending on its condition.

On the off chance that it's one of the 40%-silver collector's coins that accidentally was spent, it would be worth about $8 for its silver content.
