Especially considering some of these coins came from a lot seized from the FBI agents (Carl Force was one) who tried to pocket it during the Ross Ulricht case. ;) The risk of something unethical happening here isn't just high... it's already happened to this exact merchandise.
And with the blockchain permanently recording this stage of those coin's provenance - I'm wondering whether owning them is going to solve or cause problems for someone later... "That's a Silk Road bitcoin!!!" (I wonder if "Real Satoshi Bitcoins" will one day be worth many times their "face value" like Confederate Half Dollars?)
If my wallet contains 10 bitcoins, and I somehow end up with a Satoshi bitcoin, don't I now have 11 bitcoins that are all alike? When I go to spend one bitcoin, how do you know if it's the Real Satoshi one or if it's one of my others?
