About this app

Silver Hallmark ID - Assayer helps you identify silver hallmarks, marks, and pieces from a photo.

●Identify silver hallmarks from a photo
Take a close-up of the hallmark with your camera or pick one from your gallery, and add a photo of the whole piece for better results. Assayer analyzes the marks and suggests the most likely silver standard, maker, assay office, period, and object type.

●Clear results you can understand
Get helpful details like the piece name, silver standard (sterling, Britannia, 800, coin silver, or plate), maker's mark, date or era, region of origin, and similar candidates so you can compare and feel more confident.

●See an estimated value range
When the whole piece is visible, Assayer provides an estimated resale value range, plus similar listings currently for sale online so you can compare asking prices. These estimates are for informational purposes only and may vary depending on condition, weight, authenticity, market demand, provenance, and region.

●Save and organize your finds
Every identification is saved to your catalog. Browse it by origin, era, object type, or value, revisit past results, and share a result card with friends.

●Great for
・Home & storage: inherited silver, unknown marks, drawer and attic finds
・Shops & markets: antique silver, flatware, jewelry, teaware, and collectibles
・Travel & discovery: estate sales, flea markets, thrift shops, and auctions

●Worldwide hallmarks
Assayer recognizes marks from many traditions—British, European (800/900), American (sterling and coin), Japanese, and more—including maker's marks, assay office marks, date letters, and standard symbols.

●Notes & accuracy
Assayer provides informational results and may be inaccurate. Identification results and value estimates are not guarantees of authenticity, authorship, age, origin, or market price. For formal appraisals, authentication, insurance, resale, or legal matters, consult a qualified professional.
