In this Timeless Moments episode, Russell and Adam dig into one of the darker sides of the hobby — market manipulation.

From shill bidding on eBay to inflated comps, they break down how sellers can game the system and what that means for collectors. The discussion covers alleged practices tied to mega-sellers like Probstein, the risks for buyers, and how platforms like eBay and PSA play into protecting (or failing to protect) the community.

The guys also speculate on Probstein’s move to launch his own platform, what this could mean for the auction landscape, and whether the balance of power is shifting between marketplaces.
