Mulberry
generalDate code & serial
Mulberry does not use a public alphanumeric date code the way some houses do. The primary internal marking is a serial number etched onto a brass roundel/disc (usually paired with the engraved Mulberry tree logo, often on or near a leather tab). Modern bags typically carry a serial; older pieces (some early Bayswaters) and factory-outlet bags may legitimately have no serial at all. A serial alone neither confirms nor condemns a bag: Mulberry has no buyer-facing serial-lookup, and known counterfeit serials are recycled and published on auth blogs (e.g. widely circulated numbers such as 258798, 275288, 373140). Treat the serial as one data point, checked for etch method, font, and disc finishing, and cross-referenced with the physical bag and paperwork.
What to checkConfirm the serial reads as fine LASER-ETCHING (shallow, slightly grey/frosted, even depth) rather than deep mechanical engraving or a hard stamp. Check the digit font matches Mulberry's clean style with even spacing. Inspect the brass disc: the tree should have crisp negative space between the leaves and a correctly shaped trunk. Cross-check any 'Made in England / Turkey / China' interior tag against the era and model (all three are legitimate on modern bags; only ~30% of current production is England). Do NOT reject a bag solely for lacking a serial, and do NOT treat a matching serial as proof, since fakes copy real formats and recycle numbers, corroborate with lock, hardware, stitching, and leather.
Red flags & tells
Cross-head (Phillips) screws on the Postman's Lock
generalMulberry's Postman's Lock and hardware plates are commonly secured with small flat-head (slotted) screws, so cross-head or haphazardly seated screws are a frequently cited tell. Investigate rather than treat as a verdict: hardware sourcing varies across eras and good fakes increasingly copy the slotted screws, so flat-head screws are not themselves proof of authenticity.
Deeply engraved or stamped serial disc instead of fine laser etching
generalAuthentic serial discs read as lightly laser-etched (shallow, frosted). Counterfeits often cut the number deep or stamp it hard and frequently get the digit font wrong. Deep, dark, or clumsy engraving with an off font is a flag, though better fakes replicate the shallow etch, so pair with font, tree geometry, and hardware checks.
Light, hollow-feeling Postman's Lock or mismatched hardware finish
generalThe genuine lock is dense solid metal with a smooth finish and evenly spaced 'Mulberry' engraving. A flimsy, lightweight lock, smudged or uneven lettering, or a lock whose metal tone does not match the other hardware are flags. Do not assert an exact weight, judge heft comparatively against the rest of the bag's hardware.
Poorly rendered Mulberry tree on the disc/logo
generalThe tree should be delicate with clear negative space between the leaves and a correctly proportioned trunk. Blobby foliage, filled-in gaps, or a distorted trunk suggest a copied die. Compare leaf and trunk shape against a verified reference of the same era.
Messy, uneven, or thick stitching and wandering edge paint
generalAuthentic stitching is straight with uniform stitch length and consistent edge width along handles and leather edges. Thick, wandering, or uneven stitching and inconsistent edge-paint width are flags of lower-grade assembly.
Off-centre or wrong-font heat stamp
generalThe 'Mulberry' heat stamp on the leather tab should be crisp, in the correct clean sans-style font, and reasonably centred. Wrong font weight, smudging, or misspelling are flags, avoid treating minor placement variation as decisive, as genuine stamping is hand-applied and not perfectly uniform.
Plastic or low-grade logo tab / thin tinny buckles
generalLogo tabs and plaques should be leather/metal, not plastic; buckles and stamped hardware should feel substantial with clean branding. A plastic logo element or thin, tinny buckles are flags.
The honest caveat
General guidance to assist a human authenticator and rule checks, not a standalone verdict. Web-checked July 2026 against Handbag Clinic (handbagclinic.co.uk), BagVanity, and general auth-guide consensus; these corroborate the laser-etch disc, flat-head screw tell, colour-matched hardware, delicate tree with negative space, and the England/Turkey/China manufacturing mix.\n\nCAVEATS / where tells fail: (1) Serial numbers are NOT a lookup-verifiable ID, Mulberry has no public buyer-facing database, known fake serials are recycled and published, and legitimate older/outlet bags may have no serial. Never pass or fail on the serial alone. (2) 'Made in England only' is a MYTH, modern Mulberry is made in England, Turkey and China, so a non-England tag is not itself a fault. (3) Country/era changes: manufacturing mix, tag wording, lining style and hardware suppliers (e.g. branded vs. RiRi zips) have shifted over time, so tells must be matched to the bag's period against a same-era reference. (4) Superfakes increasingly replicate the flat-head screws, disc etching, and lock heft that older guides relied on, so no single tell (screw type, weight, font) is decisive, corroborate across lock construction, hardware finish consistency, stitching/edge-paint, leather grain, and paperwork. (5) Avoid absolutes: do not assert a bag 'always' weighs a set amount, that the stamp is 'always perfectly aligned', or that any single feature 'proves' authenticity.\n\nNo specific serial-number format, font name, factory code, or measurement is asserted, per high-stakes rules, the disc/etch descriptions are kept at system level and marked general. Recycled fake serial examples are cited only as known-bad references, not as an authentication method."
