How to Identify Silver Hallmarks & Year of Manufacture
- 1). Examine all of the silver's stamps. Using a jeweler's loupe is helpful to see very small stamps and details of stamps. View each stamp from different directions so that you do not try to identify the wrong stamp. Marks can look different if they are viewed sideways or upside-down.
- 2). Determine the nature of the stamps found. The four types of stamps you might find are a purity mark, a maker's mark, a dateletter and a town mark. The purity mark indicates the purity of the silver, typically fine silver or sterling silver.
- 3). Examine the maker's mark. In many European countries, manufacturers are required to include both a purity mark and a stamp that identifies the silversmith, but the United States does not require silversmiths to sign their work.
- 4). Inspect the dateletter. Silver items made in England after 1478 were stamped with a dateletter, indicating the date the item was assayed by the government.
- 5). Examine the town mark. Silver items assayed in countries with multiple offices often included a town mark to indicate the office of assay. For example, an anchor is the assay mark of the office in Birmingham, England.
- 6). Compare the marks you find to the marks of known silversmiths. Narrow your search by researching in a book or on a website that concentrates on similar silver items.
