Mutations, Value, and Item Grading

Mutations and item grading are the main reasons a normal auction find can become a serious payout. Use them carefully: mutation bonuses add together, while grading can either reduce or increase final value.

Quick Tip: Check mutation tags before selling. Dirty lowers value, while Secret, Void, Hologram, Chrome, Timeless, Gem, and Diamond are high-priority holds.

Mutation Basics

Current public mutation data says multipliers are additive, not multiplicative. If one item has Silver and Gold, add those bonuses together instead of multiplying them.

BandMutationsHow to treat them
Top valueSecret, Void, RainbowHold and inspect before selling
High valueHologram, Chrome, Timeless, Gem, DiamondStrong sell candidates and tracker priorities
Mid valueCorrupted, Wet, Shocked, Ancient, Firefly, GoldGood profit boosts during normal auction loops
Low or riskDirty, Cobwebbed, Pure, Moonlit, Silver, Huge, Tiny, AntiqueUseful only when attached to a strong base item; Dirty lowers value

How to Improve Mutation Chances

  • Place Gavel Trophies before auctions when you are intentionally hunting better mutations.
  • Pay attention to weather because some mutations are tied to conditions.
  • Increase luck through drinks, accessories, net worth, collections, gamepasses, friends, and gavel boosts.
  • Use the Time Capsule after reaching the reported $100,000 net worth unlock.

Item Grading

GradeReported value effectDecision
Replica55% of original valueBad outcome; avoid gambling weak items
1 Star85% of original valueSmall loss
2 Star135% of original valueGood upgrade
3 Star200% of original valueHigh-value result worth celebrating

Grading is not free value. It can lower the sale price, so use it most carefully on items where the upside is worth the wait or gem skip.
