Foamy:

The twisted berlin has another sale here at 53

so it appears it may not be appropriate to value that at 150 here, not even with the cap as implied here. 150 is an outlier for it. You could use 47-53 or 53 flat as a mini for it here. Taking 53 would put the sale here at ~200, so I would make this 200 flat.

The eldritch bowl has another sale for the tesla KE, grove bat and the other items (see https://backpack.tf/suggestion/61ccc8d178a52e3cf4444edc ), which would require a KE update or at least an appropriate mini on it (and the bat hat, though the KE is the most important part here), but it supports the raise here at least. Id put this at 200 flat and then give the bowl a range with this sale and the KE sale after the other hats have been updated.

Untrace, guessing bulk

Possible sales at 47 and 150, buyers at 53 and sellers 85-95, very inconclusive.

Taking 53 here as Foamy suggested.]

Adding up everything else gives us 24.5+83+20+20+53=~200 keys
