Silver hallmark identifier

Decode the marks on your silver & gold.

Photograph the stamps on any piece and Hallmark ID reads the assay office, date letter, standard, purity, and maker — a transparent five-mark breakdown, plus a live melt-value estimate.

A lighter, more accurate mark-decoder — not a shallow value guess.

Most apps look at the object and guess a price. Hallmark ID reads the punches — town mark, date letter, standard, and maker — and matches them against a finite, transparent reference database. You see the reasoning, not a black box.

Point & scan

Line up the marks, and scan

Frame the hallmark inside the scanner reticle and capture. Reading starts right on your device using Apple Vision — no account, no waiting. Snap a fresh photo or pick one from your library.

Five-mark breakdown

Every mark, explained

Instead of a bare verdict, you get a structured card: which punch is the assay office, which is the standard, which date letter gives the year, and which maker's mark it is — each mapped to a record in the reference database.

A confidence badge tells you whether a mark was read on-device or needs a manual check — the app is honest when it isn't sure.

Melt value

See what it's worth to melt

Enter the weight and Hallmark ID estimates the melt value from the current silver or gold spot price and the decoded purity. A quick, transparent read for thrift finds, estate lots, and inherited pieces.

Estimated from the live metal spot price — an estimate, not a guaranteed appraisal.

Three steps to a decode

1

Snap the mark

Frame the punches in the scanner and capture, or choose a photo from your library.

2

Decode the punches

Marks are read on-device and matched to the reference DB — assay office, date letter, standard, purity, maker.

3

Value & save

Add the weight for an estimated melt value, then save the piece to your collection.

Made for collectors, dealers & flippers

Purity & standard

925 / sterling, EPNS & plate, and gold karat — read straight from the standard mark.

Assay office & origin

Town marks decode to the assay office and origin of the piece.

Date-letter year

British date-letter alphabets decode to the year — the hard part, done for you.

Maker's mark lookup

Match the maker's-mark punch against the reference database.

Worn-mark fallback

Pick the closest punch by hand when a mark is faint or a symbol — no fabricated guesses.

Melt-value widget

Live silver & gold spot and your collection's estimated melt value on the Home Screen.

Questions

What does Hallmark ID actually tell me?+

It reads the punches and decodes the assay office (town), date letter (year), standard mark, purity, and maker's mark into a structured five-mark breakdown, then estimates the melt value from live spot prices.

Is the value a real appraisal?+

No. Hallmark ID is an estimate and decode aid, not a guaranteed appraisal. The melt value is derived from the live metal spot price and the weight you enter.

Does it work on worn or faint marks?+

Many marks read fully on-device. For faint or symbol punches you can use the manual "pick the closest punch" fallback, and the app flags low confidence instead of guessing.

Do my photos leave my phone?+

Scanning happens on-device first, and many scans never leave it. Only for low-confidence marks is a single image sent to a secure server-side proxy to help read the punches; it is not retained afterwards. See our Privacy Policy.

Which regions does it cover?+

The reference database focuses on UK and major-European hallmark systems in this version, with more coverage planned. Obscure provincial or foreign marks fall back to the manual picker.
