ebay finds that PWCC engaged in shill bidding?

I just looked into this further since I'm basically being called an idiot for my statement regarding these not looking fishy at all from a data perspective.

You state that these sales are "all far above actual sales contemporaneous to them". This is not true. These sales are all very much in line with the other sales for this card. I looked up all sales of this card in any grade going back to November 2020 on both Terapeak and PWCC's Market Research Tool. The list below is comprehensive. Every sale in this dataset lines up with market expectations. Also worth noting is that the middle sale of the 3 in your post above is absent in both eBay's Terapeak research tool and PWCC's research tool, which generally implies that it was not paid for. Perhaps that listing was shill bid by the person who previously bought it for 11k? Who knows. But it makes perfect sense for it to be listed again if whoever bought it did not pay for it.

Note the sale of another PSA 9 by some random ebay seller on June 5th, just 3 weeks before the most recent sale of the 3 you posted. It sold for $5911 at auction, but there were at least FOUR unique bidders all of whom placed a bid north of $5k in that auction. The one you say was "far above actual sales contemporarenous" to this one sold just 3 weeks later in the same PSA 9 grade (but with an older style slab) for $4861.90 at auction with PWCC.

Here are the sales of this card. All of these line up perfectly with expectations given the market trends we've seen throughout 2021.
