The CS20 Collection is the weapon collection of the CS20 Case, added to the game in 2019. It holds 17 weapon skins, from Mil-Spec Grade to Covert. SkinsMonkey lists every CS20 Collection skin with prices for each wear level.
The CS20 Collection is the set of 17 weapon skins tied to the CS20 Case. Every skin in the set shows The CS20 Collection in its in-game details. The case also drops the Classic Knife as its rare special item. Knives are not part of any collection, so you will not find it in the list below.
A trade-up contract takes 10 skins of the same rarity and returns one skin of the next rarity up, picked from the collections of the skins you put in. Fill the contract only with CS20 Collection skins and the result is always a skin from this set. StatTrak and regular skins cannot be mixed in one contract. Since the CS2 update of 22 October 2025, five Covert skins can also be exchanged for a knife from the collection of one of the skins used. With five Covert skins from The CS20 Collection, the knife comes from the CS20 Case pool.
The CS20 Case page covers the container itself, and all CS2 collections are listed on one page.
