I asked Mike at The Antler Collector for an appraisal of these sheds; you can use his response as a track to run on if you have a large set you might want to sell sometime:
Split G-2 hurts the net…Stain, ouch, not good news. And pen-raised deer have swallowed up the prices up on the wild racks. An antler like this would need to be sold on Ebay in my opinion. He would get between $125 and $300 if lucky. A lot of 220- to 250-inch sheds sell on Ebay for $175 to $300, so it’s a tough call. These may only bring $100.
