This is a tricky case. One of the reasons it is so tricky, is because it was suggested when this sale was almost outdated already. At the time, 3 more sales happened. I cannot trace the sales, but judging by the people that bought and sold them, I am very confident that all 3 of them will have been a lot lower than 42 (2 of them sold to bots and the other one was R+ubi selling it, who typically does not list that much above what he buys for).

The question here would have been whether we would see the clean version as selling higher because it's clean, or because its spelled, and the problem with that is that we can never really be sure - in fact, the truth likely lies in the middle somewhere. I suppose that if this really had been the only sale in its time frame, I would consider accepting (although even then, I would be hesitant due to the time the dupe has been unsold for, especially since the gap is so large).

In this case however, it seems to be that the other clean sales (very likely) imply the sale at 42 is an outlier even for this specific instance of the item.

I suppose I could be persuaded if the other sales do indeed also support this value, but with all I see here I think there is too much to imply this sale is an outlier.
