We had a buck on our farm now several years ago that looked very much like that. We called him "King" because his one antler looked like a crown. I don't know what happened to him though, he was all over the place one year and we passed him up many times.
We never saw him the next year though. I am not sure if his rack grew normally the next year or he died, etc. I mention this only because you indicated that he would make an unusual mount in a few years.
