What you get
• Browse 17,000+ marks four ways: by date letter, by object, by animal, or by shape. Whichever lane matches the punch in front of you.
• Date-letter lookup for London, Birmingham, Sheffield, Edinburgh, Chester, Dublin, and Glasgow. Pin the exact year a piece left the assay office.
• Maker's marks and assay punches show town, working years, and metal standard at a glance. Useful when you're trying to tell a Hester Bateman from a 1920s revival.
• Save favourites and pull them up fast on the next estate-sale visit. The marks you check often stay one tap away.
• Second opinion reader: point your camera at a punch and get a candidate match drawn from the catalogue. Use it as a shortlist, then confirm against the full record.
• Plain-English glossary of trade terms. Assay, duty mark, lion passant, sterling, britannia, town mark, date letter. Newcomers can follow what dealers are saying.
Rebuilt from the ground up natively for iOS 18. Faster, cleaner, organised the way you actually look up a mark. Photos load instantly. Search is sharper. Favourites sync across your devices.
