Maybe you should point out the mistake to him and see what he says
I sent the seller this message:
I noticed that the coin you have listed is in a PCSS slab and you state that it is PCGS. Surely this is a mistake. Thanks!
This was the response:
Yup an error. Thanks I will fix it
They did change the title to PCSS, but not the Item Specifics. I won't push it any further.
