I was looking at my old coin books today and found that some time in the last 56 years I inserted this one. Is it an error of some other phenomenon? I have never run into this type of strike before. Could it be a 1954? @FredWeinberg
The last number in the date (1) has damage from a coin rolling machine. Common in that era. I have a couple myself.
Copper is fairly soft and moves quite easily. If you were to take a flat blade screwdriver you could “push” the number one and make it lean left or right fairly easily.
Pictures are bad. but looks like soemone shaved most of the 4 of a 1954
Welcome to the forum!
1951 with post mint damage on the last 1.
Not really sure I’m ready to call mint errors “phenomenon “ 🙃
