we all know the KN planchet, you can spot a KN penny from a mile off just looking at the obverse, however a strange one happened today, bought a bunch of coins (was a nice VF+ first type george was 1917 but thatw as by the by) as in packaging it came in stapled stuff to keep them seperate, however this one red looking worn penny had moved behind the 1917, (so i couldn't see the date) first thing i thought was, hey a KN, got in... took it out, turned it over... 1919, no letters at all. now i possibly have seen old 1912 H filter through to 1913. but never something like this. screenshots will come at some point soon BUT was wondering if anyone knows about such things.
