Rare I g as he coin has been peeled, it's not worth near as much as it was when intact. Being said, it may be worth more than a standard edition peeled coin but not by much.
I've also peeled one of mine just because I was curious to see inside. I don't think I've actually redeemed the DOGe from it though.
Exactly what I did, never knew the value would decrease drastically
Guess I'll wait a few years
What did you expect? It is a coin, not even made of precious metal, with a hologram on the back. Under that hologram, as clearly stated when you bought it, is a private key to the public address. All you have left is a redeemed coin, it has lost most of it's value and it's very unlikely the to increase in price by much even after a few years.
