We still need to see the public address to verify funds, that's unfortunately just a piece of brass in the eyes of buyers.
I'd recommend posting it on the collectibles board if you are interested in selling.
I was also thinking about it, as far as selling it for BTC, you may actually fetch a higher BTC premium as the price of BTC is down now. You can look into selling it for BTC and hodling liquid BTC until the price goes back up.
Oh no, I'm not selling. Not for a long time. :)
