I wanted it due to the age of the coin being over 100 years old and that it was struck on the wrong type planchet.
I did some research on the US Mint's involvement with Argentina. Yes the US mint assisted - BUT the US Mint only provided planchets to Argentina.
They were made at the Philadelphia mint.
They were planchets intended for the 10 Centavos coin
The total number of pieces made were 3,443,334
The planchets consisted of 75% copper, 25% nickel
Each planchet weighed 3.0 grams
The diameter of each coin was 19mm
The gross weight in grains per coin was 46.29707
No idea how many were struck on a US coin type design.
The other one I do know of is one of these that is graded MS65.
