Hermès Constance (24) entered the record around 1959: structured shoulder bag, oversized h clasp, in box, epsom or exotic leathers, with palladium or gold-plated hardware and the h turn-clasp.
The H-clasp shoulder bag whose birth year the histories split between 1959 and 1967 - the file marks the dispute rather than settling it.
The model has remained in the maison's catalog across eras; this file anchors on its documented history and makes no claims about current lineups or prices, which is why it reads the same in ten years.
The introduction is marked circa because the documentation is: fashion houses publish far less history than they manufacture, and the file records the range the evidence supports rather than inventing precision.
The full collector's file for this model, era details, and the authentication walk-through are on the writing schedule; the record above is permanent.
Hermès sits at the summit of the counterfeit economy: the Birkin is the most faked luxury object on earth and superfakes carry plausible blind stamps. The doctrine: a blind stamp is not authentication. Date it with the stamp tool, then demand era agreement everywhere - saddle stitching, hardware engraving, heat stamping, leather grain and stamp placement all have documented histories. At these prices, professional authentication before purchase and platform authentication in transit are both part of the price, not extras.
