About the UMP-45 | Gold Bismuth
UMP-45 | Gold Bismuth is a Restricted skin that drops from one of the 42 CS2 weapon cases, the Operation Broken Fang Case.

Each open has a 3.1960% chance (about 1 in 31) of pulling it, as one of 5 Restricted finishes. One in ten of those drops is StatTrak.
It sits in tier 2 of 5 (Mil-Spec to Rare Special) and ranks #35 of 41 finishes in the Operation Broken Fang Case by top-wear Steam price.
Its Steam price runs from $3.31 to $20.82 across wears, against $10.65 to open the Operation Broken Fang Case (case plus $2.50 key), so 1 of its 5 priced wears are worth more than one open.
