was there any known problems with the 1957's in particular?

i have run into quite a few 1957's with various die breaks, on the date, and "liberty" as well as a few on the motto. here is a fairly odd one with a break inside the loop of the 9, and something extra on the tail of the 9. it almost looks like extra metal, which also may have taken some kind of a hit. just a coin for sharing. I'm sure it is not af any particular value, other than a sort of odd die break. thanks.
