At minimum I'd guess these are genuine NGC cores. The wider tabs holding the coin were used for a period of time in the past. The three vs four is based on coin size what does and doesn't get it. Experienced collectors would know but are even they prepared to look for that and expect it? The labels are obviously images grabbed off of NGCs site and printed out to roughly the same size (but not the same quality). Inserted with fake coin into what may be real NGC slabs and cores. Yep, if you weren't vigilant before you better be now! Doesn't look like they're discriminating. Thank you for posting this! Will add it takes a real scum of the Earth to do this and I would vote for 17th century style penalties for the perpetrators.
I haven't been successful getting Coin World's attention in several past attempts... NGC does mark the on-line certs with notes for reported counterfeits; PCGS not so much.
I'm sure the TPGs want to minimize the prevalence of altered/faked slabs in the media. Best course of action would be making the NFC chip STANDARD across all services.
As damaging as this is to the hobby I can't fathom why CW, PCGS or others would balk at getting this type of thing in front of everyone. It should be 'page 1' throughout the hobby.
Staying with a theme... This one was just listed on the Bay; seller's on the left, NGC images on the right. See anything missing?
Unfortunately, as bad as this last one is people are bidding on it... https://www.ebay.com/itm/3745696898...84&osub=-1~1&crd=20230317174612&segname=11001 This seller had several bad gold "coins" for sale that were removed; I plan to post them in another thread over the weekend.
@Jack D. Young thank you for your diligence staying on top of these criminals. Lots of people questioned why I started this thread..... https://www.cointalk.com/threads/our-beloved-coin-collecting-hobby-is-becoming-discouraging.403438/ The advanced technologies these criminals are employing to deceive us is becoming an incredible burden for the casual collector. I'm relatively sure most of the members here do their due diligence before buying anything numismatics related. And yet I'm also sure many of us are still taken for a ride. So sad.
