I bought it for 5 pure and a Strange Killstreak Degreaser with a 2.5 key Strange Part.

Strange KS Degreasers usually go for ~40 ref.

Since mine had that Strange Part, it's safe to assume its worth was nearing a whole key, so I'm rounding it up to 6.

Only one registered sale on mp.tf was in January, so it's irrelevant.
