1917 Antique British Threepence Necklace | 18ct Gold-Plated Sterling Silver
A British threepence dated 1917 forms the pendant. The original coin shows the portrait of King George V on one face and a crowned numeral three within a wreath on the other. Its date and struck details remain visible, alongside the individual surface marks of a coin that has circulated. It is a genuine antique threepence, not a modern reproduction.
The coin is mounted in sterling silver and finished in 18ct gold plating, with a coordinating plated chain. The warm colour frames the coin’s relief while keeping its original design at the centre. The coin measures approximately 16 mm in diameter.
Choose an adjustable chain that fastens at 16, 17 or 18 inches, or select a fixed length of 16, 18, 20 or 22 inches. The choice changes where the pendant sits, whether worn alone or with other chains.
Every necklace features an individual antique coin, so subtle differences in tone, wear and surface marks are part of its appearance.

How can we help?
Contact Roberts & Co for a question about a piece or an existing order. Please include the product name or your order number where relevant.
Delivery & returns
Find current delivery information, destinations and estimated timings in our delivery guide. For eligibility, time limits and the steps to return an order, please read our returns policy.
Find your fit
Use our ring sizing guide before choosing a size.
Chain lengths
To compare lengths, measure a necklace you already wear from end to end, including its clasp. Alternatively, use a soft tape to judge where you would like the chain to sit. A pendant will hang below that point. Available lengths and dimensions are shown on each product page; contact us if a measurement is missing.
Common chain lengths, with centimetres rounded to one decimal place: 14 inches (35.6cm), 16 inches (40.6cm), 18 inches (45.7cm), 20 inches (50.8cm) and 22 inches (55.9cm).
A fixed-length chain has one wearable length; an adjustable chain offers the fastening positions stated in its description. Check the options for your chosen piece, as available lengths vary. How a necklace sits also depends on your proportions and the pendant’s dimensions.

Choosing a coin
Dates, denominations and struck details give genuine historic coins their individuality. Read the description and photographs of your chosen piece for its coin, setting, chain and finish.
Choose care to suit the material, finish and construction of your piece. Start gently, and ask a professional jeweller if its condition or materials are uncertain.

Everyday care
- Put jewellery on after perfume, cosmetics and hair products have dried.
- Remove it before bathing, swimming, exercise, cleaning and activities that expose it to knocks or chemicals.
- Store pieces separately to limit scratching and tangling. Check clasps, links and settings for wear.
Gold-plated jewellery & vermeil
A plated finish needs gentle care. After wear, wipe lightly with a clean, dry, soft cloth, without vigorous rubbing. Store dry and separately in a soft pouch or lined compartment.
Avoid silver dips, abrasive cleaners, polishing compounds, hard brushes and ultrasonic cleaning. Do not use a silver polishing cloth on a plated surface. The gold layer will change gradually with wear; its longevity depends on use and contact.
Sterling silver
Sterling silver can tarnish through exposure to air, moisture, cosmetics and chemicals. For suitable plain, unplated silver, use a silver polishing cloth gently. Mild soap and lukewarm water may be suitable for sound, plain pieces; rinse and dry thoroughly.
Do not apply this advice to gold-plated, oxidised, antique or delicate stone-set silver. Aggressive polishing can remove patina and soften detail.
Solid gold
For sound, plain gold jewellery, mild soap and lukewarm water with a soft cloth can remove surface residue. Rinse carefully and dry thoroughly. Check the requirements of any stones, settings or other materials first.
Historic coin jewellery
Preserve the coin’s struck details and signs of age. Avoid abrasive polishing, dips and attempts to remove patina. A coin, setting and chain may need different care; for a plated coin, follow the gold-plated guidance above. Seek advice before cleaning an antique or fragile piece.
Gemstones & pearls
Care varies by stone, treatment and setting. Do not assume ultrasonic or steam cleaning is suitable. Porous and delicate materials, enamel and glued elements need particular caution.
Wipe pearls gently with a soft, slightly damp cloth after wear. Do not soak or scrub them. Keep them separately from harder jewellery and avoid prolonged storage in very dry or airtight conditions.
When to seek advice
Stop wearing a piece if a stone is loose, a clasp is insecure or a link or setting is damaged. A professional jeweller can assess its condition before cleaning or further wear.
