Like the guys said above check the pedicles.But the one shed looks really chewed on and the other minimal.Either the rodents are real bad where the first one dropped or the other one was dropped alot later.I would think with headgear that size he would want that antler off as fast as possible to get his head balanced again so it could be two.But they do look like pretty much like a perfect set.Either way there is a monster lurking in your woods.
