It is only considered advertising or self promotion (as far as our rules are concerned) when the person posting is also the person selling. Posting links to someone you think is a good dealer or seller is not only NOT against the forum rules, we encourage you to do so
It's disgusting that these coins bring the amount of money they do. People have to be absolutely blind looking at these things. There is no way a coin like the one in the OP sells for more than like $75-100 to a dealer raw. The one in my profile pic ending up grading AG3 with NGC but it is on another planet compared to many I have seen lately. Unfortunately the pic I have makes it look not great but hopefully I'll get a nicer high res one soon. I've been really tempted to try cracking it and sending to PCGS with the amount of wild grades I've seen from them lately. If you really want a laugh, look at the greysheet prices for Liberty Cap cents. AG3 - $75 and G4- $300.... It's been like that for months, while people are paying $100 over sheet for awful looking coins.
I believe the way you worded this makes people think this is your site.. I did as well. You say "I have", "pm me", etc. confusing.
