Is this REALLY a detached Leg Buffalo
Happy Sunday everyone.
I'm not into errors; but in a box of odds n' ends, I found this piece this morning. I'm not sure how much the ANACS label will show (not-so-hot photography shills...sorry) but it is a 2005 S Detached Leg, Cameo Proof 68. I looked online for photos but I couldn't determine if this was a legitimate "detached leg" or not or if perhaps ANACS made a slight error. Your guidance would be appreciated. It will be destined for eBay but I want to be sure it's legitimate first.
Also, is there a site that gives an approximate value for error coins such as this? I didn't find one.
As always, thanks so much!! I have attached 2 photos.
