The hair area was a common place for the die to start cracking (as seen on your coin) and eventually pieces of the die would break off and cause corresponding raised areas like this on the coin. They start as small die "chips" and progress to larger die "breaks." I believe this one may be big enough to be considered an "Interior Die Break" or IDB.
