How it helps
Use it for a focused task
A single-page hallmark reference and lookup workspace for thrift shoppers, estate sale browsers, and new resellers. Users enter observed marks, metal color, weight feel, magnet reaction, and likely era to get probable meanings, common fakes, and next-step testing ideas.
The page also includes a long-form reference section with comparison tables, example scenarios, common mistakes, troubleshooting, and FAQs. Inspect the piece under good light with a loupe or phone macro.
Type any visible stamps into the Hallmark field. Add metal color, weight feel, magnet reaction, and era if known.
