No 1964-D Peace Dollars left the mint either, according to the mint. Just like the '33 Saints, there are going to be a couple that pop up in more than a few years. I know where one is rumoured to be tucked away - the one that was given to the person responsible for their being minted in the first place.
The OP is discussing the Aluminum cent from Denver though. As for the 33 Double Eagles they were authorized to be struck before the they were ordered to be melted (destroyed). The 64D if memory serves was in the same as the 33 DE's. If a 64d would be found I'd bet the Mint would want that back also
But the point is, the mint doesn't exactly know what happened. Wouldn't be the first time and it sure won't be the last.
It just seems like a waste of good tax payer money to try and get these coins back...at least to me. Wouldn't we be better served to allow them to sell and then collect income taxes off the revenue generated? But...I guess it's not the first (nor the last) time tax payer money is wasted. But then, on the other hand we don't want to encourage people to steal government property and sell it.
But then see the K-Job thread, there are some people that justify theft because it is some big entity.
although I do agree that mint workers and relatives of mint workers should have it confiscated from them, if someone not at all affiliated with the mint winds up finding a coin of like circumstance, and especially if that person is too young to have even been born yet when said coin was made/left the mint, then they should be allowed to keep it.
There is no justification of this. None. The mint is just bullying collectors because they can. It's a huge waste of money and resources, and what purpose does it serve? It doesn't hurt anybody if Joe Blow has a '33 double eagle or a '74 aluminum penny in their private collection. Victimless "crimes".
