Buy a sac Birkin 40 Hermès

From the pieces handled by Monogram (data as of 15/08/2026): Birkin: middle half between 17 400 € and 23 500 € (median 19 900 €, 11 pieces, 5 sold); Birkin 25: middle half between 22 000 € and 24 000 € (median 23 000 €, 5 pieces, 2 sold). These are market estimates from a small sample, all leathers and conditions combined, not guaranteed prices; other sizes have too few observations to be detailed.

The Birkin 25 is currently the most sought-after size (for city use, with high demand and limited supply). The 30 remains the classic everyday size, the 35 is suitable for office/weekend use, and the 40 for travel or masculine use. The Sellier finish (visible stitched edges) is rarer than the Retourné finish.

Interior blind stamp (letter in a circle, square, or rhombus depending on the year), workshop code engraved under the stud of the front straps, regular saddle stitching with waxed thread, padlock and clochette stamped with the same number, gold-plated brass touret plate with clear marking. Each Birkin is inspected at Monogram Paris by Entrupy analysis, followed by a manual review by a leather goods expert.

A Birkin's value varies with size, leather, colour, hardware, condition, accessories and demand at the time of sale. No return is guaranteed: Monogram's published Birkin value page shows the available observations, with their period and sample size. At Monogram Paris, every Hermès Birkin 40 is authenticated then offered with its certificate, and can later be bought back or taken on consignment.

Each piece is examined by our expert firm (Entrupy AI-assisted analysis, complemented by a manual review for leather goods). Stitching, hardware, markings, date code, and accessories are checked one by one. A Monogram Paris certificate of authenticity is provided to the buyer.
