The 4 Essential British Silver Marks

Standard antique British sterling silver carries four or five distinct stamped marks:

Maker’s Mark: Initials of the silversmith or manufacturing firm inside a distinct cartouche.
Standard Mark (Purity): The Lion Passant (walking lion) for Sterling Silver (925), or Britannia (seated figure) for 958 silver.
Assay Office Mark (City):
- London: Leopard’s Head (crowned prior to 1821, uncrowned after).
- Birmingham: Anchor symbol.
- Sheffield: Crown (prior to 1975) or White Rose (after 1975).
- Edinburgh: Castle symbol.
- Chester: Sword and three sheaves of wheat (discontinued 1962).
Date Letter: A single letter designating the year the item was tested at the assay office.

How to Read Date Letters

Date letters run in 20-year cycles (excluding letters I, J, N, O, Q, V, W, X, Y, Z depending on the specific office).

Font Style: Gothic, Roman Script, or Sans-Serif font styles differentiate cycles.
Shield Shape: The border shape enclosing the letter changes every 20 years.

Distinguishing Sterling Silver (925) from Silver Plate

Many items marked EPNS (Electroplated Nickel Silver), Quadruple Plate, or Sheffield Plate are not solid sterling silver.

Expert Advice: Solid British sterling silver will always bear the Lion Passant or Britannia standard mark alongside a town mark. If an item only says “SILVER”, “925”, or “EPNS” without town marks, it is either non-British or silver-plated.
