There on the "B" in liberty also on the number "9" in 1955 if i can get better pics ill try too on the mint mark "D" looks doubled or a cud on the reverse the right mid part of the wheat also has a cud
OK, if they are on the letters and numbers they would be die chips not cuds. I can't really make them out in the pictures but die chips are very common on cents of the 1950's.
1955 is a common year to find very minor Die Chips on the numerals and letters. Really not much of a big premium. No more than $1.00
