Are these mugs safe for drinking?

Many older pewter items contain lead within the alloy mix, which can leach into acidic or alcoholic beverages over time. It is generally advisable to treat them as decorative display items rather than daily drinking vessels. Plated or twentieth-century Arts & Crafts pieces may pose fewer risks, but testing for lead content is recommended before actual use.

How do I identify a tavern measure?

English public house measures usually display official verification marks, touchmarks, and stamped capacity indicators like pint or quart on the rim or body. These stamps ensured customers received accurate quantities of beer. Inns often stamped their own names or the landlord's details directly into the metal surface for local identification.

What is Old Sheffield Plate?

Old Sheffield Plate is an early form of plating created by fusing silver and copper together under heat before rolling them into sheets. This method preceded electroplating and results in a rich appearance where the base copper occasionally peeks through worn highlights. Tankards made from this material combine the lustre of silver with the sturdy rigidity of copper.
