I can only speak for myself...
Mine go for more...
The good thing is most want them for a full body mount so you have an outlet for ones that don't turn out huge...They can be sold just on color alone then people can add a different antler.
Based...on color you can make a sale...
The bigger the antler of course the bigger the bonus!
Speaking what I've dealt with you can add from $700.-$3000. or more but that is the norm. just because of color!
