My price suggestion is set to 60-80 keys (which backpack.tf says is about $100, which is what I bought it for)

Proof of sale (before parts were applied)

This item sold for $100 on marketplace.tf recently.

Cheapest listed on scm (with the same effect and also strange) is priced similarly, sales on scm are also similar to my price suggestion. for example, one sold on scm (on january 5 2026) for $91 usd, which is similar to the sale price.
