OK.. Back to Lyrics You do know that the normal non plated Presidential Dollars do not contain any kind of gold.. especially Nordic gold (which is gold-coloured copper alloy) as you stated? https://en.wikipedia.org/wiki/Presidential_$1_Coin_Program Composition - Copper with manganese brass cladding: 88.5% Cu 6% Zn 3.5% Mn 2% Ni
You might get a response after Monday.. Tomorrow is Labor Day and I'm sure they are off I'm curious.. What would you do then if you found a Plated Presidential Dollar? You turn it in to the Feds?
Definitely would not be interested in buying. I already know that it is not a legal tender. That is as far as I would go. It is not my style to turn in anyone. I understood the law and It is clearly written and I'm just going to express my opinion if I'm ask. Definitely will protect myself from these fake novelties.
I believe @TheFinn is correct about the manganese. There were many articles in the coin publications leading up to the release of the Sacajawea dollar. I recall reading that the Mn was added to keep the electronic properties the same as the clad SBA to appease the vending machine industry. It had nothing to do with the strength or wear resistance of the alloy. And it had nothing to do with corrosion resistance as evidenced by the rapid discoloration of the alloy
