The big drivers

These factors apply across most categories.

Condition

Wear, repairs, missing parts, chips/scratches, and functionality all impact value. Honest details + photos help us price accurately.

Verification

Stamps, serials, hallmarks, and certificates reduce risk and guesswork—often leading to a stronger and faster offer.

Completeness

Original box/papers, receipts, accessories, and matching documentation can improve accuracy and resale demand.

Market demand

Brand desirability, style trends, and current wholesale demand can move offers up or down week to week.
