Our Wuropean ancestors would use the antlers in rituals of shamism, spears, or to catch fish with and in bartering. Humans have been using these for bartering like money all based on the majesty of the animal and skill of being a hunter. I've seen new artists distespectfully use animal hides and antlers, whichbia disagree with morally. The only other thing I can think of is if OP would make a fishing tool out of growing as a person for survival and to pass the skill onto his own children. They also make enduring handles for knives.
If he uses it as decoration most inner citu normies would either shreek or ask if he hunted….if OP says "I found the antlers" than the antlers will probably have a negative connotation since he doesn't have the skill to accomplish a hunt and kill of an elk/deer on his own.
OP kind of sounds like a teenbro by collecting something like this with no purpose. Mistakes of youth.
