Only 4 ref matches on the seller's end. Manually searching similar IDs shows more metal being involved.

For my sanity, i'm not gonna find all the metal involved. This should be enough evidence to prove more metal was involved.

These sales are going to end up being 15+ keys at the least. These will be excluded, due to the magnitude of pure sales for cheaper.

Sellers/Buyers:

https://backpack.tf/item/7236505867 - 10 keys

Buyers at 8 keys

Sales at:

8

8.5

9 (2x)

13

+ 3 marketplace sales at 15+ keys.

Despite it being a pure sale, 13 is going to be too high, given the seller at 10 keys, and the large amount of sales for much cheaper. Excluding 13. Marketplace sales are a very weak support of a cheap item's key value, so I will not be using the marketplace sales as support of the 13 key sale.

Many buyers at 8 keys, excluding 8.

Taking 8.5-9 keys.
