Hermès 2026 bags marked with 'G' date stamp — Collectors

Hermès aficionados and resale communities are buzzing over the first confirmed date stamp for 2026: the letter “G.” The mark, discreetly embossed inside Birkin, Kelly, and other leather goods, signals the year of manufacture. Typically hidden along interior panels or under straps, it’s designed for authentication rather than display, helping collectors and buyers verify provenance.

The blind-stamp system has shifted over decades. From 1945 to 1970, Hermès used single letters to mark years; 1971 to 1996, letters appeared inside circles. From 1997 to 2014, the brand switched to squares before returning to plain letters in 2015. Alphabetical order is no longer strictly followed, a move to make counterfeiting harder. Recent codes include B for 2023, W for 2024, K for 2025, and now G for this year.

Hermès doesn’t officially release its codes, leaving boutique sightings and resale verification as the main sources. The 2026 “G” stamp matters not just for authentication but also for resale value and collectibility. Certain years or stamps can signal limited editions or rare leather runs, giving savvy collectors a potential edge. For those tracking investment potential, knowing the 2026 marker ensures accurate dating and pricing of Hermès pieces on the secondary market.

The “G” stamp is already shaping how buyers and collectors approach Hermès this year, confirming that even subtle details can carry major weight in luxury circles.
