I own the square tail but have yet to see the other variety.
I am guessing the square tail is the most common of the 2 types?
Do 2 types even exist or is the square tail the only type? I ask since my world coin price guide shows 2 types (not images just values).
Based on what I am seen so far round tail's don't seem to exist. Some Eagle tails ''seem'' longer but that is about it.
