At the German forum at https://www.numismatikforum.de/viewtopic.php?f=6&p=552223#p552223 there is a message from January 8, 2022 about a Pertinax that is apparently a fake: Triton XXV Online Session 5 (25-26 Jan 2022) It is lot 5392 at https://auctions.cngcoins.com/auctions/4-4HLNK9/triton-xxv-session-5page=9&limit=48 Should cng be notified?
Yes, please do notify them. They are both honorable and reputable. They will pull it and keep it locked away if it is. Though, that provenance gives me pause... Here's my real...ly worn authentic one:
Both those Pertinax coins in the current auction have been through some pretty expereinced hands with some very long pedigrees
The arguments at the German forum are very well founded. Just sent CNG an email. Maybe they can take a closer look at the coin. If I hear back from cng will let you all know. I am just very worried about so many fakes showing up at different venues.
I'm not saying they're wrong. Surprising since it is a plate coin. Been seen by a lot of experienced people.
..the CNG coin is legit....the rest are copies...(in my opinion)..i have a couple, one is similar to that type, but enough variations to see its not a clone..
Actually, on the German forum they argue quite convincingly that the CNG coin is a fake, and indeed one of several Pertinax fakes offered by CNG over the years. I can't judge, but it would be quite worrying if a reputable dealer like CNG cannot identify these fakes.
Here is a montage of four coins from the Forvm Fakes database. The first coin in this montage was identified as being the potential host for these fakes. The G at the end of the obverse legend is damaged on the top coin and this damage is evident on all the other coins. This top coin looks more convincing as the host than the CNG example to my eyes.
My first thought was that the CNG coin must be legit because the border on the right side of the reverse is off the flan of the original. Then I noticed the weak scales and the S in COS on the reverse, and now I'm thinking it's a copy. It it is legit, then it's a double die match--not impossible, especially for a scarce coin--and the damage must have been in the die. Glad I don't have to make this call.
I would think the first step would be to see the reference Lempereur Type 7, 252a (D82/R140 – this coin) to determine if this is actually "this coin". Also, someone here must have the Peus 366 catalog to see if it matches all those edge splits. I am regularly wrong but I would have expected the faker to fix that short G while they were fixing those cracks if, in fact, the CNG coin is the mother of the rest. It is a shame to declare a good coin fake but this one sure seems to be bad.
Finally the lot was withdrawn. In French we say: « faute avouée est à moitié pardonnée ». My poor translation: « confession of a fault, is half redressed ».
