what does this symbol mean?
An anchor in a shield

Anchor (Birmingham hallmark)

The mark of the Birmingham assay office: the piece was tested and hallmarked in Birmingham.

How to read it

The UK’s Hallmarking Act lists an anchor as the mark of the Birmingham assay office, and Chaffers’s 1922 list of assay office marks gives the same. Jackson notes that gold assayed at Birmingham has carried the same marks as London gold, except that the anchor takes the place of the leopard’s head.

Also searched as: anchor hallmark, Birmingham assay office mark.

A stamp is a claim about the metal, made by whoever struck it. This page says what each mark means under the rules that define it; it doesn’t test or value anything.
