1764-D Prussia 1/12 thaler not in catalog [επιλυμένο]

I was helping a friend of mine catalog some coins, and we stumbled on this. The coin matches with this type (https://en.numista.com/catalogue/pieces23927.html), yet there is no D mintmark listed. Taking a look at Krause, you can see there are two 1764-C listed but no 1764-D. Since it's the same type and the same mintmark listed under it twice, I assume this is a typo and one of them should be D. But proof of the coin is below so if you believe it's a counterfeit or something you can make that judgement. The coin did come from a reputable auction house so it should be authentic.

Indeed, Krause does not list it but it does exist.
Mintmark D for coins minted in the town of Aurich. I have added it for you but cannot verify now if others with mintmark D are missing on this coin sheet.

​Thanks for adding it.
