To understand the CS2 skin market – and make better decisions when you buy or sell CS2 skins – it is necessary to examine all these factors together rather than focus only on the skin’s listed rarity. What determines CS2 skin prices? Case and collection supplyEvery skin originates from a case, collection, souvenir package or limited event. Low-tier souvenir items can remain inexpensive and may even be considered cheap CS2 skins because many copies exist. Anyone participating in the CS2 skin market should evaluate the exact item rather than rely on a general market listing.
