I find it very interesting that when graded the original is labeled "1oz .999 silver" and this one is labeled "silver"
Wonder if any testing is done to confirm it is actually .999 silver when it is labeled as such?
I'd highly doubt it. Most probably they're going with what they see, graded "as seen".
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?
I am 100% sure. This is a fake coins
Maybe you missed the original discussion back then, we already know these 2016 coins are knock-offs/replicas.
The OP also states this fact.
