My first post here.
I've come across this MNH strip of five King George V Medallion 3 cent (Scott #197c) in an old tin that's been in the family for a long time. In looking at one of the stamps in the strip I see this noticeable mark on the King's neck. None of the other stamps in the strip have it. Is this of any interest/value? Or is it just a boring blob of ink?
Thanks for any ideas or thoughts.
