Is this a doubled die

Hello and welcome to Numista!

Doubled dies are as the name implies “errors” in the die.  Since the dies are used to make thousands to tens of thousands or more coins each true doubled die (as opposed to machine doubling) especially for US coins is well documented. The first step is seeing if other doubled die coins have been reported for that denomination, year and mint and what they looked like.
