There's a sale before these two

It sold alongside the Infernal Wraith Patriot Peak, looks like strx dumped their PE Stahl + Scorching Santa + Miami Reggae to D-Mav the same day to buy both. The Uncraft Rack + ~13 keys + Minigun kits + Dead Head also went to SerafeTTiN. This is potentially a bulk buy but worth checking.

As for Sale 2, the keys seem to match to Graphite_Taco, who sold their Eldritch Opening Vampire Vanquisher, so I'm not sure all the 100 keys are part of this trade - meaning 175 is probably not correct.

If I had to guess, I would assume the Vampire sold for 100 keys, and Jimp traded their Purple Energy Patriot Peak for the Specter Patriot + Phantom Crown Chill Chullo in a 2:1, so the sale is potentially 177.5 - 106.5 = 71 keys

71 matched the highest buy order at the time https://gladiator.tf/listings/624d1962d3322e818c596b67, so I guess maybe the Patriot was valued at buyers here. It would also mean this sale is bulk (i.e. Specter Patriot's value was <50% of the trade for the Purple Energy Patriot) so it should be excluded anyway. Taking 110 flat seems to make more sense here.
