Antique Letter Seal
An antique letter seal is a small desk accessory designed to impress personal insignia into hot wax, securing correspondence before the widespread use of gummed envelopes. When you search for an antique letter seal, you encounter practical implements and decorative desk seals originating from periods such as the Georgian, Victorian, and Edwardian eras.
The pieces on this page span several centuries and styles, taking the form of desk seals, desk accessories, and wax seals. You find portable fobs, desk sets containing coloured-glass seals, and combined desk rulers or bougie boxes that house sealing wax.
Origins and periods represented include Georgian, 18th Century, Victorian, Edwardian, and the early twentieth century, alongside specific pieces showing Middle Eastern influence. These objects range from simple steel fobs to elaborate novelty forms featuring animals and jesters.
How they were made
Materials utilised in these pieces include sterling silver, silver, steel, and brass, often paired with glass for intaglios or accompanied by sealing wax, velvet, and paperboard packaging. Metal components are cast, cut, or shaped into intricate forms such as horse heads, hatching chicks, and Cheshire cats.
Makers and workshops employed techniques like cutting steel and mounting intaglio coloured-glass seals into boxed desk sets. Combined desk accessories integrate silver holders with original sealing wax for functional desk use.
Listings feature sterling silver, steel, and brass, alongside sealing wax, velvet, and paperboard across Georgian, Victorian, and Edwardian periods.
What varies in quality
Quality in these pieces is determined by the crispness of the intaglio cutting, the weight and purity of the metal such as sterling silver, and the preservation of original elements like sealing wax or boxed sets. Elaborate novelty figural work demonstrates higher sculptural skill than plain geometric forms.
Makers' marks and hallmarks add documentary weight, while complete boxed sets with multiple interchangeable glass seals represent a higher tier of desk equipment than single detached fobs.
