Checker

Checker isn't performing as well as it used to, it generally struggles to get base downgrades in good demands, and generally only gets base in low-mid demands (which is quite bad for an item that's considered average). This is quite avoided too unlike other average items.

Duped Checker, similarly to its clean variant, is also not that good in trading currently. It often struggles to get base in good demands, and hardly gets any offers to begin with. Checker in general isn't particularly looked for, however the duped variant specifically isn't looked for at all, hence the demand is quite low for it.
