The 2021 Train Collection

All collections

The 2021 Train Collection released on 21 September 2021 with Operation Riptide. It is a Souvenir collection and a genuine sleeper: it holds the M4A4 The Coalition and a Souvenir Glock-18 Gamma Doppler, including the Emerald variant.

Most people forget this collection, but the top items are worth four figures.

Skins by rarity

Every skin is Souvenir only, and the Covert tier is unusually deep.

The rare item: M4A4 The Coalition

The Coalition is a gold and black paint job with interlocking triangles and blue highlights, a bold geometric Covert. Factory New copies trade around four figures, and the collection also holds a Souvenir Glock-18 Gamma Doppler, which is a Doppler finish on a pistol, plus the Emerald phase at the very top.

"Train 2021 is the sleeper: a Souvenir Glock Gamma Doppler and a four-figure M4A4 hide in a map collection most people forget."

Where the skins come from

These skins came from Operation Riptide in 2021, tied to the Train map. There is no standard case, and the collection is no longer produced.

Trade-up contracts

Since the 2026 souvenir trade-up change, souvenir skins from this collection can be used in trade-ups toward the next tier, up to the Covert. The inputs are pricey and the odds long, so the expected value is negative.

As a collector item

This is a discontinued, low-supply map collection with a surprisingly strong top end. The Coalition and the Souvenir Gamma Doppler give it real collector interest that its low profile hides. Buy to hold.
