Lacy,

Welcome to the forum. First a doubled die is not a double struck coin. Die doubling happens in the hubbing process and double struck happens on the coin during the strike. 
 

This coin just exhibits some worthless doubling. It’s common on coins and is not a doubled die, error, or variety. 
 

Here is a good starting educational piece from our hosts.

That is just DieDeterioration from a worn die. No premium for it.
