This is the printable one-page flow for “I have a bag and want to know if it is real.” Each step branches to the relevant detailed page in /authentication/ for full evidence and caveats. No single check is sufficient; era-consistent answers across creed, country, serial, hardware, and construction are required before a bag can be called authentic.

Step 1 — Is there a leather creed patch?

See creed-formats.md for the full era-by-era breakdown.

• No creed, but a small metal interior tag → likely E2a (early 1960s). Continue with no-creed authentication via leather, hardware, and construction; creed-based steps below do not apply.
• No creed, no metal tag, just a leather stamp inside → likely E2b through early E2c (late 1960s through early 1970s). Same caveat — skip creed-based steps and rely on hardware, leather, and lining.
• Yes, a leather creed with a serial → continue to Step 2.

Step 2 — Does the creed read “COACH LEATHERWARE”?

See creed-formats.md §“Key textual anchor”.

• Yes, “COACH” with small-caps “LEATHERWARE” stamped beneath → pre-1994 (E3 or E4 era). Continue to Step 3.
• No, just “COACH” (LEATHERWARE absent) → 1994 or later (E5 or modern). Continue to Step 3.

Step 3 — What does the country-of-origin marking say?

See country-of-origin.md for the full progression and the 2003 10-K-confirmed sourcing list.

• “Made in New York City, U.S.A.” → 1970s through circa 1980 (early E3). Should pair with LEATHERWARE wording.
• “Made in United States” / “Made in U.S.A.” with LEATHERWARE present → 1980 through 1994 (late E3 into E4).
• “Made in Costa Rica” / “Hungary” / “Turkey” / “Dominican Republic” / “Mexico” → 1994 through early 2000s (E5). Should pair with the LEATHERWARE-absent creed.
• “Made in Italy” → exotic-skin or Madison / Gramercy line; Italy is line-specific, not era-specific.
• “Made in Puerto Rico, U.S.A.” → through April 2002 (Coach’s Lares facility, the last in-house plant, ceased production April 2002 per coach-10k-fiscal-2003).
• “Handcrafted in China” → 2000s onward; post-vintage for this archive.
• Era-inconsistent combination (e.g., LEATHERWARE wording with “Made in China,” or “Made in New York City” with an offshore origin) → fake or replacement creed. See country-of-origin.md §“Era-inconsistency = fake”.

Continue to Step 4.

Step 4 — What is the serial format?

See serial-numbers.md for the full decoder and the single-digit-year ambiguity discussion.

• All digits, e.g. xxx-xxxx (1970s) or xxxx-xxx (1980s) → pre-1994. Should pair with LEATHERWARE wording and US origin.
• Letter-digit-letter-dash-digits, e.g. B6D-9927 → 1994 onward. The year position is single-digit (1994–2003) or double-digit (2004+).
  • Single-digit-year ambiguity flag: B6 resolves to 1996 or 2006 depending on decade. Resolve via creed wording (LEATHERWARE absent for both readings, but transitional 1994–1996 pieces sometimes retain it), country of origin, hardware, and lining. Never publish a year reading from the code alone.
• No serial at all → era-context dependent. Pre-1980 bags, small accessories, and some 1990s pebbled-leather models legitimately shipped without serials. Absence is not by itself a fake tell; era expectations come first.

Continue to Step 5.

Step 5 — Hardware

See hardware.md for the full discussion of brass, turnlock construction, and the dogleash clip.

• Magnet test: brass is non-magnetic. Magnet sticks → likely fake or plated-steel replacement hardware. This is the single fastest authentication check.
• Weight and color: solid brass is heavy for its size and develops a warm honey-to-amber patina at handled spots. Light weight, silver/grey underlayer where the surface has worn, or uniform “factory-new” plating on a 1980s bag are fake tells.
• “COACH” stamping: appears on later turnlocks and dogleash clips. Absence on Cashin-era (E2) or early E3 pieces is expected, not a tell. Stamped-out (rather than cast) turnlock bars and casting seams on the dogleash body are stronger fake tells than stamping presence or absence.

Continue to Step 6.

Step 6 — Construction

See leather.md for material and edge treatment, and lining.md and zippers.md for further diagnostics.

• Edges: raw or burnished on vintage Coach. Glossy painted edges on a bag claiming pre-1995 manufacture are a strong fake tell.
• Smell: glove-tanned leather has a distinct neatsfoot/leather odor. Acetone, strong plastic, or chemical-solvent smells are fake signals.
• Lining: unlined raw-suede interiors are correct for many NYC-era bags (Court, Willis, etc.); heat-cut polyester pockets on a pre-1995 bag are a fake tell. See lining.md.
• Zipper maker: should be era-consistent with the creed. YKK on an E2 or early-E3 creed, or Talon on an offshore E5 creed, is a mismatch worth investigating. See zippers.md.

Continue to Step 7.

Step 7 — Aggregate the red flags

• 0 red flags + era-consistent across all checks → likely authentic.
• 1 red flag in a single dimension (e.g., a wrong-era hangtag alone, or a lone replacement zipper) → possible replacement component, not a fake on this signal alone.
• 2 or more red flags in independent dimensions → fake or Frankenbag. Do not buy without significant additional verification.

Replacement-component caveat

Coach Repair (consolidated at the Jacksonville, Florida facility from July 1999 per coach-10k-fiscal-2003) replaced creeds, hardware, hangtags, zippers, and other components during legitimate restoration work through the program’s lifetime. A “wrong era” component is not automatically a fake — it may be an authentic bag that went through Coach Repair. The caveat applies in isolation; once two independent dimensions disagree, the replacement explanation no longer covers the evidence.

Transitional-period caveat (~1994–1996, plus Lares through 2002)

The LEATHERWARE wordmark dropped in late 1994 and offshore production ramped up across 1995–1996, but the transition was not instantaneous. Two specific transitional patterns are real and should not be flagged as fakes on era-mismatch alone:

1. LEATHERWARE-present + offshore country (~1994–1996): stock bodies stamped with the older creed sometimes finished at offshore facilities once those facilities came online. Era-mismatched on the wordmark/country axis, but a documented transitional manufacturing artifact.
2. LEATHERWARE-absent + “Made in Puerto Rico, U.S.A.” (1995–April 2002): Coach kept the Lares, Puerto Rico facility producing under the new creed wording until April 2002 [coach-10k-fiscal-2003]. “Made in Puerto Rico, U.S.A.” is U.S. origin under the creed-side country marking but pairs with the LEATHERWARE-absent post-1994 wordmark. Not a contradiction.

Wizard verdicts will flag both patterns as era-mismatched. Treat the verdict as a prompt for second-opinion authentication rather than a fake declaration when the bag’s other signals (hardware, leather, construction) are otherwise era-consistent. The conservative reading is: an era-mismatch verdict on a bag that fits one of these two patterns is a request for human review, not a verdict of fakery.

When in doubt — community authentication

If the seven-step flow above does not resolve the bag, post the canonical photo set to PurseForum’s “Authenticate This COACH” thread (purseforum-authenticate-coach). The photo set required for any second-opinion request is listed in counterfeits/index.md: full bag (front, back, both sides); creed close-up with a ruler in frame; turnlock front and back; zipper pull and tape stamp; lining and any interior tags; country-of-origin stamp; hangtag both sides; base and feet.
