I have noticed that the 1921 penny I have is different to the 1920 (don’t have 1922 to compare) it’s my understanding this is the order in which they run 1918 1918H 1918KN 1919 1919H 1919KN 1920 1921 1922 1926 Second Type - Modified Obverse 1926 Third Type - Modified Reverse 1927 Fourth Type - Obverse Modified Again 1928 1929 And so on Take a look at the GRA:BRITT on the obverse the gap is different (between the colons) looks more like the 1926 So my question is this was the coin revised or is this just the result of die types
