Type
Hollowware
Maker
William & James Dealtry. They were prominent silversmiths registered in London during the late 18th century, known for high-quality domestic silver including mugs, goblets, and tea service items.
Material
Sterling Silver (.925 purity). Solid throughout with no base metals or mixed materials visible in the hallmark area.
Dimensions
Standard Georgian half-pint or pint capacity depending on the specific vessel body. Estimated weight for such pieces typically ranges between 200g to 450g (6.4 to 14.5 troy oz).
Description
A fine example of George III silver craft, this piece showcases the understated elegance of the late 18th century. The clarity of the Dealtry maker's mark suggests a piece that has been well-preserved and not over-polished, retaining the crisp edges of the original London assay strikes.
Key Features
Distinctive 'W.D / J.D' maker's mark and the presence of the crowned leopard, which was replaced by an uncrowned version in 1821, making this a definitive pre-1821 antique.
Material & Composition
Sterling Silver (.925 purity). Solid throughout with no base metals or mixed materials visible in the hallmark area.
Finish & Decoration
Mirror polish with minimal decoration, characteristic of the Neoclassical or early Regency transition. The focus is on the reflective quality of the hand-raised silver surface.
Hallmarks & Stamps
Full British London Hallmarks: Maker's mark 'W.D / J.D' (William & James Dealtry), Lion Passant (Sterling purity), Leopard's Head Crowned (London Assay Office), and Date Letter 'D' in a pointed shield.
Construction Details
Hand-raised from a flat sheet of silver. The hallmark area shows slightly uneven surface texture consistent with historic hand-planishing and striking of punches into solid metal.
Functional Features
Liquid vessel; typically features a reinforced rim and a robust base for stability in daily dining use.
Handle & Grip Details
Likely a scrolled or 'C' shaped solid silver handle, traditionally attached via high-lead solder joints at the top and bottom of the body.
Craftsmanship Details
Superb hand-wrought evidence. The marks are deeply struck, indicating the metal was annealed correctly, and the surrounding surface shows the slight 'firecoat' variation expected of 18th-century silver.
Authentication Indicators
Hallmark consistency is excellent. The depth of the Lion Passant and the alignment of the maker's mark in a rectangular cartouche are perfectly consistent with known examples from the Dealtry workshop in 1799.
Origin & Manufacturing
London, England. Produced in the West End or Foster Lane silver quarters under strict Worshipful Company of Goldsmiths regulations.
Era & Period
Georgian Period (specifically late George III). Characterized by the use of crowned leopard heads and specific shield shapes for date letters typical of the late 1700s.
Age Estimate
Circa 1799. The specific combination of the 'D' date letter and the crowned leopard's head aligns with the 1799-1800 assay year.
Cultural Significance
Represents the height of British silver standards during the Napoleonic Wars era, where silver served as both functional art and a portable store of wealth for the rising merchant class.
Condition Notes
Very Good. The surface shows light 'use' scratches (patina) but no evidence of heavy repairs or 'ghosting' around the hallmarks, which indicates the silver hasn't been thinned by excessive buffing.
Value Estimate
$800 - $1,500 USD for a single mug; significantly higher if part of a set. Value is driven by the rarity of the makers and the excellent strike of the hallmarks.
Care & Maintenance
Gentle hand cleaning with a high-quality cream like Wright's or Hagerty. Avoid ultrasonic cleaners or machine polishing which can blur the crispness of the 225-year-old marks.
Similar Pieces
Comparable to works by Hester Bateman or Peter & Ann Bateman from the same decade, though Dealtry pieces often feature slightly heavier gauge silver.
Interesting Facts
The Dealtry family were reputable makers often commissioned for 'official' silver and high-end domestic ware; pieces from this year are often sought after for the clear strikes of the final year of the century.
