What's even worse is that it takes no specialized expertise or skill to see that the bar codes are different (as @Mr. Numismatist noted) and "REIGN" falls across the center post of the scale graphic at two very different locations.
It's a $1500 ish coin if it was genuine, and the melt value would be just over $400. People are trying to get a deal, but they're not looking at it closely. The font itself is oddly wide on the counterfeit label. I was able to call eBay and talk to someone. There were several details on the coin that are notably wrong that are describable even to a layperson, and visible in these mediocre photos.
Yeah, fonts are an easy tell. Many slab counterfeiters don't match the original font. And even when they do, as in this case, they don't get the weight of the font right.
https://www.ebay.com/itm/156049551720/ The seller is back with a new zero feedback account listed from a different town in Poland. Same photography and a new fake gold coin in a fake NGC slab. Please report this one.
https://www.ebay.com/itm/176311645010 Same fraudulent seller. This coin is a horrible fake. I'm embarrassed for whomever bid on this one. It doesn't even look real from a distance. Please report this. EBay's AI in its infinite wisdom doesn't see anything wrong...
I ended up calling their customer service line too. The auction was up around $1800 last time I had checked and I didn't want someone getting ripped off. They ended up taking it down.
