When you get into these situations, value becomes very subjective. For example, I recently found a somewhat worn 1946 nickel with a well known
DDR. Jefferson's bust on the obverse has some abrasions across the whole face. Maybe without the scratches that was a $40 coin. PCGS would almost certainly grade it Details with Scratch or Damaged, and might even hit me with Cleaned for using acetone to remove a bunch of gunk.
Is that nickel worth $40? No. But I bet someone would give me $10 for it. The
DDR features are worn but obvious, and both identification markers are present. The scuffing is on the front, all the important stuff is on the back. At some point, the value is low enough to where some people probably don't worry about resale value, and primarily decide to buy based on whether they like the coin and want to keep it. I've bought many rocks and minerals in the $5-25 range based on that exact mental process. I never gave a moment's thought to whether I could ever resell that nice pyrite crystal or Herkimer diamond.
If it's a $3000 coin with a
Ring of Death, then you might be out of luck. But I still bet someone would give you more than $0 for it. If it's an interesting and non-obvious feature like a doubled die (vs. a CAM/WAM or something easily understood), then someone might give you a few bucks just to own one.
Why not post it here for id and grading, and see what people say?
