Sometimes (back in the old days), people would bite down on a coin to see if it was genuine. Looks like teeth marks to me.
It probably didn't hurt it's value much, since it's probably worth melt. It's worth about $2.50 according to my 2013 Blue Book. That's the buy price, but I wouldn't think it would sell for any more than the $3.50 you'll see at most coin and antique shops.
