There was no poll option for 5 cents. 68-69-70 they made S nickels for circulation. So even though they are not as common as the other nickels, it's 5 cents unless it is in ridiculous condition.
It's a keeper if you're collecting from circulation. It will be a long time before you find a nicer one with less wear.
Welcome to CT and it's worth face value some day by chance It might increase but I'm not sure. Thanks, Jacob
