Gold coin auctions: sovereigns, bullion and historic gold, searched at once

Gold coins range from modern bullion Britannias, Krugerrands and sovereigns bought largely for their metal weight, through to genuinely historic and scarce issues, medieval nobles, hammered gold, and pre-decimal sovereigns with premiums for date, mint mark and condition, so the same search box needs to catch bullion resellers and specialist numismatists alike.

Why gold coin lots get missed

A historically significant gold coin, a medieval noble, a scarce sovereign date, or an ancient gold issue, can be listed by a general seller who only recognises it as "gold coin," with no idea of its numismatic premium over simple bullion value.

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 coin type, "sovereign," "gold bullion," or "gold 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 "gold coin": genuine gold Britannia bullion alongside a rare Edward III gold quarter noble, 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 dates you collect

Save a search (a coin type, a date, or "gold 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 gold coin lots before adding the rest of the platforms via the extension.

Built for how gold 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.
