Value of 2013 1oz Silver Eagle Proof w Case?

The coin in question was a proof sold by the mint direct program likely and its from W (West Point) and indeed a proof, not from a green tube. It looks like you have handled it or someone has I see a fingerprint or smudge either on the coin itself or the circular case. That white paper they call the COA (Certificate of Authenticity) . As for the price we see them selling regularly for between $45 and $60 at online market places. If you are selling to a dealer however they always pay less, since they have to turn around and resell and make a profit to keep the lights on. Your best bet is to try and sell it directly, but if you don't have experience doing so it might take some time. Hope that helps, thanks for posting. So yea between $40 and $60 as of early 2025.
