I was going some CRH today and I came across a 1968-D Lincoln Memorial Penny with a 2 and 4 stamp mark on the sides of Lincoln's face. I can't find anything on it online and my local shops are closed for the weekend. Any ideas????? Thanks!
Sine they were not done by the mint, but by post mint damage, they could represent birthdays/anniversary, the 2 numbers missing 50 million lotto winnings, or by a workman, testing the sharpness of his punch set. One person had 1000 stamped with the date of his divorce and spent them all over a city. Punch sets are so much fun.
