Collection trade-up research
The Achroma Collection matters for trade-up planning because collection membership changes the output pool, not just the cosmetic theme. A contract using Achroma inputs can roll next-rarity skins from this collection according to the collection weights represented by the 10 input skins. That makes rarity depth, listing supply, float ranges, and floor prices important signals when comparing contracts. Use the rarity sections below to see how many skins are available at each tier, which weapons appear in the collection, and where the cheapest active listings start. For profitable trade-ups, CSAlpha combines these collection details with real marketplace prices, deterministic output-float math, CSFloat, DMarket, and Skinport data, then links the live opportunities on the dedicated collection trade-up page.
