Cobblestone Pin

The Cobblestone Pin is a collectible pin that was originally distributed as a physical pin at Valve-sponsored CS:GO Majors and some official events, with a redeemable code for the in-game version. In CS2, you generally obtain it by buying the collectible from another user on the Steam Community Market or third-party marketplaces if a marketable version is available. New in-game drops for this pin are not part of the normal CS2 item drop system.

CMB usually refers to the Collectible Pins Series 3 capsule, not the Cobblestone Pin itself. The Cobblestone Pin is a separate collectible tied to the Cobblestone map theme, while CMB is not the standard abbreviation players use for it. If you mean the in-game Cobblestone Pin, it appears in your CS2 inventory as a collectible pin item rather than a weapon skin.

A Genuine Cobblestone Pin code was the redeemable code included with an official physical Cobblestone Pin from Valve event merchandise. Redeeming that code granted the corresponding in-game Genuine-quality pin to a Steam account. Unused genuine codes are limited because each code could only be redeemed once, which is why sealed or unredeemed pin items are discussed separately from standard market listings.

The price of a Genuine Cobblestone Pin depends on whether you mean the in-game Genuine pin, a sealed physical pin with an unused code, or a standalone unused code. Sealed physical pins and unused codes usually carry a premium over a redeemed in-game item because the supply is much smaller. Check live listings carefully, since sellers often describe these variants differently and that changes the valuation significantly.
