The best kinds of trades are ones which both participants are happy to forego their asset in exchange for the other.

I have no idea what the value of the punk I purchased from you will ultimately be, heck it might even just become a value-less trophy item. But the important thing is I value that, and thank you for selling it at a price I deemed worth the money.

I'm not sure if other trades of similar value or more have happened -and I think this would be a useful feature to have at some point- but hopefully as more people tender the amounts asked and more collectors show up, there might be some real legs behind all this!

Thanks @derangedvisions and thanks @themarkymark for a wonderful experience!
