he deleted my comments also so I will paste them back here.
I've never sold through Heritage, Stacks, or GreatCollections, so I can't speak on anyone's contracts. But I have met Pia and worked with her a bit while she was cataloging my own work for my collectors, and she's always seemed kind, professional, and genuinely supportive of the space.
Also, "up to 50% over spot" is very different from a 50% seller commission.and you say "up to" and "not for you"

That could mean $1k commission on a $50k+ sale for them depending on the outcome and they are assuming risk also, no? Anyone can just kindly choose to sell elsewhere without trying to promote a boycott.
Heritage brings a level of reach and legitimacy that most niche platforms simply don't have, especially for something as small as physical Bitcoin collectibles. Constructive criticism is fair, but also be careful about attacking one of the few major auction houses willing to champion this category at all.
Why do you keep deleting my comment:
Honestly man, I just think this is getting a little overly personal toward Pia specifically. She's an employee doing her job and seems genuinely passionate about the category. I'd hate for someone googling her for whatever reason years from now to find a thread attacking her over policies she likely doesn't even control.
