Wonder if any testing is done to confirm it is actually .999 silver when it is labeled as such?
Original Sol Noctis carry an "Ag 999 1oz" engraving on their face, hence that's what ANACS writes on the slab.
I got no idea how this knock off could get labled as silver (Those certainly aren't silver coins, neither do they say anywhere on the coin "Silver", "Ag" or sth similar),
maybe someone at ANACS googled what Sol Noctis are made of or they just took a guess?
The OP also states this fact.
