The MP9 | Dark Age is a Mil-Spec SMG skin from The Cobblestone Collection, distributed through the ESL One Cologne 2014 Cobblestone Souvenir Package.

The float range for this finish is restricted to 0.00–0.22, so Factory New, Minimal Wear, and Field-Tested are the only obtainable conditions on the open market. Battle-Scarred examples are not produced, so the most worn copies still retain a relatively clean appearance.

A Souvenir version is available, dropped exclusively from cases collected during Major Championship matches and stamped with that tournament's stickers. Active listings for MP9 | Dark Age are tracked across 17 marketplaces, with prices spanning $16.45 to $500.00 depending on wear, variant, and seller.
