Identifying silver & metalware.

You read silver through its hallmarks.

The silver market is saturated with silver-plated ware (Sheffield plate, electroplate) sold as sterling silver. A silver teapot by Limoges or German makers from the 19th century can be worth €1,500-€8,000, but the same style in electroplate brings only €200-€600. Hallmarks, the official seals of silversmiths, assay offices, and geographic stamps, are essential for valuation. Dutch hallmarks from Amsterdam, Utrecht, and Groningen each have their own characteristics; German hallmarks differ from Swiss ones. AntiqBot analyses the precision of hallmark stamps, the uniformity of silver alloy (925, 800, 750), and the wear patterns that reveal how old a piece truly is. Delft and other European silversmiths used characteristic initials, city seals, and dating systems. Amsterdam used a crowned seat mark until 1807, then an anchor symbol. Early Dutch silverwork (16th-17th century) is thinner and less refined than 18th-19th century pieces; the same makers evolved their techniques over time.

Electroplate appeared after 1840 and has a different chemical profile than hand-wrought silver. AntiqBot distinguishes these through spectral analysis and wear characteristics. Engraved or chased decoration on silver shows characteristic ageing patterns; modern imitations of the same ornament feel different and exhibit different micro-scratches. Assay marks indicate alloy percentage: 925 is 92.5% silver (sterling), 800 is 80% (Continental), 750 is 75% (jewellery standard). These ratios also changed by region and period. Dutch silver from 1920-1930 is typically 925, while French silver from the same period was 950. Collectors seek specific combinations of hallmark and style; a silver piece with an Amsterdam crown mark and Art Nouveau decoration from 1900-1910 can be worth two to three times more than the same piece without this combination. Weight, metal composition, and hallmark authenticity determine the price entirely.

From Belgian silver with Antwerp hand marks to British sterling with lion passant and date letter, from Russian silver with Kokoshnik marks to Scandinavian pieces with crown stamps, AntiqBot recognises the patterns across European silversmithing traditions. The system identifies maker marks, city marks, date letters, fineness marks, and import stamps. For British silver, the hallmarking system is exceptionally well-documented: each assay office (London, Birmingham, Sheffield, Edinburgh) used different town marks, and the date letter changed annually, making precise dating possible to the exact year. Continental silver uses a different system, often combining a fineness number (800, 835, 925) with a maker's mark and sometimes a national guarantee stamp. Belgian silver carries the distinctive Antwerp hand mark (pre-1868) or later Belgian guarantee stamps. This diversity of marking systems is precisely where AntiqBot's deep expertise adds value, reading silver hallmarks is a specialist skill that takes years to master.

Hallmarks are everything.

For silver analysis, hallmarks are decisive. Photograph them close-up with good lighting. A macro photo of the base stamps is always better than an overview shot of the object. Use your phone's macro mode and ensure indirect daylight, flash washes out the fine relief details of stamps.

Also photograph the overall form and any decoration, these confirm the style period. For cutlery: both front and back of the handle. For candlesticks and jugs: also the underside and any wear at the base. For jewellery: the clasp and any engraved inscriptions.
