Hallmarked silver auctions: British sterling silver, searched at once

British hallmarked silver carries a full set of marks, the maker, assay office, date letter and standard mark, that together let a buyer date and attribute a piece precisely, something no other collecting field offers so reliably. A well-known maker, an early date letter or a complete boxed set can all carry real premiums over unmarked or lightly marked silver of the same weight.

Why hallmarked silver lots get missed

General estate sellers often list silver items without transcribing the hallmarks, so a piece by a notable maker or from an early date can sit unrecognised inside a listing described only as "silver item, hallmarked."

One search across every platform

Auction Bid Assistant's free browser extension searches the-saleroom, EasyLive, Bidspotter, Invaluable, NumisBids, iCollector and LiveAuctionWorld simultaneously, alongside eBay. Search a maker's name, an assay office like "Birmingham" or "Sheffield," an item type, or "hallmarked silver" generally and results return across all of them, with images, estimates, current bids where shown, and sale countdowns, sorted by platform in tabs.

Real results for "hallmarked silver antique": genuine dated hallmarked silver items including a 1919 Birmingham cigarette case, found in one search.

It works by searching from inside your own browser, the same as opening and searching each site yourself, just done in seconds. Nothing is stored on our servers, permissions are minimal, and the extension never places a bid on your behalf.

Alerts: for the makers or assay offices you collect

Save a search (a maker's name, an assay office, an item type, or "hallmarked silver" generally) and get emailed the moment a new lot matches it, across all covered platforms including eBay, rather than relying on remembering to check each one.

Want to try before installing?

The same search box works on this website with no install at all for eBay, iCollector, LiveAuctionWorld and Featured Auction catalogues, a quick way to see matching hallmarked silver lots before adding the rest of the platforms via the extension.

Built for how hallmarked silver collectors actually work

Save any lot with one click from search results, export your shortlist as a printable PDF or CSV before a sale, and on the day itself the optional live bridge feeds the auctioneer's asking price into the free bid calculator, so your maximum (with buyer's premium and any applicable taxes included) is always in front of you.
