Early Large Cents
I was just searching for unattributable coins and came across this site. I apparently joined 8 years ago, but lost the bookmark.
I recently found an 1800 I can't attribute and thought I'd post it here.
My claim to fame (or infamy) was the discovery of the third known 1793 NC-6 while scanning the Heritage Archives looking for comps for a S-16 a friend discovered.
I confirmed this as well as a 1795 NC-3 for another friend and my purchase of an unattributed 1796 NC-2 is what I use for my avatar.
