Perhaps, although perhaps not. If this contrived sale never went through, it's possible we may never have seen those massively inflated prices thereafter, which were directly ballooned by the hype of that sale. This is in fact the entire CRUX of the ongoing litigation.
Let's just put it this way, in 2018, a year before WATA and before the crazy sealed boom, would Bronty have got over a hundred grand for that Mario? Absolutely he wouldn't. It is only BECAUSE of that wash-trade and the WATA/HA conspiracy that the rest of the overhyped, overinflated prices could have been achieved.
Sealed game collecting and grading was a thing WAY before WATA started. It's only after their shenanigans every baseball card/comic book collector and his dog wanted a piece of the action.
So, yeah, I stand by what I said, Bronty stood to gain (and in fact massively did gain) from his participation in that wash-trade.
