I was wondering if anyone can take a look at the word HALF DOLLAR (Most visible in letters F&D). I'm having trouble telling whether it is a double machining error or double die. This is the same case with the leaves of the branch on the reverse side.
P.S. I'm new to coin collecting I'm helping my uncle with submitting coins for NGC grading as he doesn't speak much english and I don't have much knowledge about coins in general and how to tell what coins are worth more than others. Where can I get started? Thank you!
