I have two Apollo X coins produced by the Danbury Mint; one is silver and the other is another metal (bronze? cu-nickel? not sure). Both coins have the same obverse (i.e Stafford-Cernan-Young with the lunar lander), but the bronze one has the wrong reverse.
Instead of having text appropriate for the Apollo X mission, it has the text for Alan Shepard's Mercury 3 mission. If it is a "mule", does anyone know how common or otherwise these would be?
