Silver coin auctions: bullion and antique silver coins, searched at once

Silver coin collecting spans two overlapping worlds, modern .999 fine bullion coins like the Britannia and Silver Eagle bought largely for their metal content, and antique or historic silver coinage, from milled English silver through world crowns and dollars, where numismatic rarity and condition matter far more than weight.

Why silver coin lots get missed

Because both bullion and antique silver coins get listed under the same broad "silver coin" description, a historically significant or scarce antique coin can be priced as if it were just another modern bullion round, and get lost among thousands of common listings.

One search across every platform: including a numismatic specialist

Auction Bid Assistant's free browser extension searches the-saleroom, EasyLive, Bidspotter, Invaluable, NumisBids, iCollector and LiveAuctionWorld simultaneously, alongside eBay. NumisBids is itself a platform dedicated entirely to coin and banknote auctions worldwide, so a single search here already reaches specialist numismatic sales as well as the general auction houses where mis-catalogued lots hide. Search a country, a specific coin type, "silver bullion," or "silver coin" 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 "silver coin": genuine silver bullion coins including Britannia, American Eagle and Kangaroo issues, 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 coins and countries you collect

Save a search (a country, a coin type, or "silver coin" generally) and get emailed the moment a new lot matches it, across all covered platforms including eBay and NumisBids, 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 silver coin lots before adding the rest of the platforms via the extension.

Built for how silver coin 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 VAT included) is always in front of you.
