How much is the Prisma Case worth?

Is the Prisma Case worth opening?
Not for the money. An opening gives back about 60¢ of every dollar in Steam Market value on average, so you lose about 40¢. That is number 1 of 42 cases by return today. Most of the value sits in the 0.9% of openings that are a Covert or better.
When did the Prisma Case come out?

Where the numbers come from
The odds are from Perfect World's published table. Each grade is five times as likely as the one above it, and a knife or pair of gloves is 2 for every 5 Coverts. The knife trade-up is in Valve's October 22, 2025 patch notes.
Prices are the lowest current listing on the Steam Community Market. Case prices are read every night, skin, knife and glove prices once a week, and the price history is Steam's own daily median. What is in each case comes from the game's item files.
Valve does not publish wear odds, so the value of a drop uses the float model players have measured, scaled to each skin's float range. Pattern and float premiums, like a Case Hardened Blue Gem, are left out. They can be worth far more than the average.
