Irish silver hallmarks

Irish silver hallmarks are associated with the Dublin Assay Office; the crowned harp and Hibernia occur in the Irish marking tradition.

Distinctive marks and standards

The sponsor punch, fineness mark, Hibernia device and optional date letter perform separate jobs. The Dublin Assay Office was established in 1637. Its date-letter sequence differs from the UK sequence.

What to check next

Read the full Irish group before interpreting a letter. A Dublin A can denote a different year from a London A. Retain the shield and typeface as well as the letter when comparing historic marks.
