What a hallmark is
A hallmark is a small stamped mark on silver that records information about the metal and where it was tested. Hallmarks help establish authenticity and long-term value for silver, collectibles and art. Typical marks include a maker's mark, a standard or purity mark, an assay office mark and often a date letter.
Key symbols to know
Lion passant denotes sterling silver. The assay office is shown by its symbol; Leopard's head denotes London assay office. Maker's marks are usually initials and help trace a silversmith. A date letter, when present, can confirm age. Together these marks let you search references or show a photo to an appraiser.
How to read a mark, step by step
1) Clean the area gently so marks are visible. 2) Use a loupe or scanner to get a sharp image. 3) Snap a close-up photo or take a scan; capture both the whole object and a tight picture of the mark. 4) Note the order of marks from left to right or top to bottom. 5) Compare the image with hallmark reference guides or use an online search to match maker initials and assay symbols. 6) If uncertain, show the photo to an appraiser.
Taking photos and scans that work
Use even lighting and a neutral background. Hold the camera steady or use a scanner to avoid blur. Make one wide image of the whole item and at least one tight shot of the hallmark so details are readable. If the mark is shallow, try raking light at a low angle to cast shadows across the stamp. Save images as clear photos so you can image-search or send them to a specialist.
Tools, references and when to get help
Start with reference books or reliable online databases that list marks by maker and assay office. For quick checks you can perform an image search or use a scanner and comparison charts. If the object is a coin, a piece of art or a high-value collectible, consult a professional appraiser for an authoritative opinion. For mobile identification, try the Antique Identifier app for scanning and organizing photos of marks.
