Sale 1: 84k, no history shared but IDs match to 7-8~ digits, e6 dumps same day and it's over unsolds so invalid regardless

Sale 2: Bot dump by e6, not shown in either compare as Vytal grabs this off bot same day

Date disparity leads to it not being seen in BigBlueBear's inv, who then gets it scammed and dumped to STN

Sales at 65k~, 72k, and 75k. Marketplace being the low outlier is a funny change of pace. While I would say it wasn't as close to the other two in terms of values, it's not that far off and had enough time sat on Marketplace that I think it's a worthy inclusion. Taking our MP sale of 64.86k rounded to 65k for the low end, and 75k sale for the high end.
