Forgive me if this Is old news (its On a 1926).... I simply don't know what to call it in order to find out what it is maybe Someone could help me out? Looks like sediment lines on the earth call parallel... Doubt Someone took a piece of sandpaper to it..... Thoughts?
Yep, or "woodies". I don't study them a ton, but they seem pretty common on cents from indian head cents up to the forties. There are some true collectors who only pursue these coins.
