Here in central Mo they lose them around Jan and Feb, I fond one directly in front of my game camera in early Jan last year, it still had a bright red blood ring so really fresh bt Ive seen them with one or both antlers still intact thru late Feb.
My friend took a dog and trained it to hunt sheds, He took him out to Co and went shed hunting for a week, nearly filled the back of a little pickup bed with whitetail, muley and elk sheds. I guess there's money to be made from them.
