If you look carefully, you'll see the majority of them were not cut off. I don't know many who want cut-off antlers. Most I see are sheds. Having the cuticle attached gives the antler realism and is also used in crafts.
Seems fishy? LOL! So if a guy and family or friends go out shed hunting and gets several pair after a season's end, he's suppose to have antler soup? Some keep the finds, some make arts and crafts from them, while others may trade or sell them.
Not sure if you thought it all out before your post, but if you think about it, there are many crafts for sale out there that involve antlers... jewelry, belt buckles, key chains, lamps, knives, plaques, etc. Someone out there selling several racks doesn't raise my suspicion... now bear gall bladders are a different matter. LOL!
