CS2 Collections: Skins, Cases and Release Dates From 2013 to 2026

This guide covers the 93 weapon skin collections on our WIKI, from the Arms Deal sets of August 2013 to Arabesque and Spy Tech in July 2026.

For each collection you get the release date, the number of skins, the rarity range and the case or package it comes from, with prices checked on November 2, 2026.

You can also browse all CS2 collections on the WIKI, where every skin has a price for each wear. The collection matters more than most players expect.

It decides which skins a trade up contract can return, which skins a Souvenir package can hold and which skins are still in a weekly drop. If you are choosing what to open, buy or trade, start with the collection and pick the skin second.

Our trade up contracts guide shows how the rules work in practice.
