Buy an authenticated Kelly 28

Across 28 Kelly bags handled by Monogram between December 2025 and August 2026 (data as of 15/08/2026; 11 sold, the others listed or offered on consignment): Kelly 25: middle half of pieces between 21 000 € and 24 000 € (median 23 000 €, 5 pieces); Kelly 28: middle half of pieces between 8 500 € and 20 500 € (median 17 200 €, 8 pieces); Kelly 32: middle half of pieces between 10 300 € and 20 500 € (median 14 900 €, 11 pieces). The other 4 pieces belong to sizes with fewer than 3 observations and are not detailed. These figures, all leathers, constructions and conditions combined, are market estimates from a small sample, not guaranteed prices: a new Kelly in a sought-after leather sits at the top of the range, a worn or incomplete piece lower.

The Kelly 25 is the most coveted size today, the 28 is the everyday classic, and the 32 is a historic size suitable for professional use. The Sellier version is rigid and structured, while the Retourné version is softer and more relaxed.

Blind stamp (year letter) and workshop marks, hand-sewn saddle stitch — even, slightly slanted stitches with evenly tensioned waxed thread —, edge finishing, matching padlock, clochette and keys, aligned turn-lock and plate. None of these details, not even the stitching, is enough on its own to authenticate a Kelly: at Monogram, every piece goes through an Entrupy analysis and a manual review.

A Kelly's value depends first on size, construction (Sellier or Retourné), leather, colour, hardware, condition and accessories. Monogram's published Kelly value page details these observations by size. At Monogram Paris, every Hermès Kelly 28 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.

Shipping within 10 to 14 working days after authentication, insured door-to-door (UPS, Chronopost). Free delivery for purchases over 1 000 €; personal handover possible in Paris by appointment.
