Nice find. Interestingly how it cracked on both sides before the right side expanded into a full cud - if it ever did, it's not listed on https://cuds-on-coins.com/lincoln-cent-cuds-1950-1958/ A roll with both a 1910 and and 1991S proof is also a cool find.
It seems like it was just luck as the other rolls in the same bundle did not produce anything interesting.
Meow was very surprised to find 115 year old penny. Now Meow will have to look in Cat Hoard for the penny album. Meow is sure the 1910 spot is empty.
Fantastic finds, especially two in one roll! Love that 54S pre cud as well. I wish you well on your health and happiness; coins and friends can be a huge help sometimes! Keep up the hunt!
