LEGO auctions: sealed sets, retired kits and minifigures, searched at once
Retired and sealed LEGO sets have quietly become one of the strongest secondary markets in collecting, some discontinued sets have outperformed traditional investments over the years they've been off shelves. The catch: they don't only turn up in dedicated toy sales. A sealed set or a childhood box of loose bricks and minifigures is just as likely to appear in a general household or "toys and games" auction that a set collector never thinks to check.
Real results for "lego": 364 lots found across every platform at once, including sealed sets and Technic kits.
Why LEGO lots slip through
Specialist toy and collectibles auctions get watched closely by the people who know what they're looking at. The value is in the lots that don't, a loft clearance with a sealed set from the 1990s, or a job lot of "assorted bricks" that turns out to include rare minifigures. Checking eight different platforms daily to catch these before someone else does isn't realistic for most collectors.
One search across every platform, plus eBay
Auction Bid Assistant's free browser extension searches the-saleroom, EasyLive, Bidspotter, Invaluable, NumisBids, iCollector and LiveAuctionWorld simultaneously, alongside eBay, a keyword like "LEGO sealed" or a set number returns matching lots across all of them, with images, estimates, current bids where shown, and sale countdowns, sorted by platform in tabs.
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: the part that matters for retired sets
Sealed and retired LEGO lots get bid up fast once spotted, so checking manually isn't enough. Save a search (a set number, theme, or "sealed LEGO" generally) and get emailed the moment a new lot matches it, across all covered platforms including eBay, where a large share of LEGO resale volume moves day to day.
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 LEGO lots before adding the rest of the platforms via the extension.
Built for how set 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.

Yes, the free extension searches the-saleroom, EasyLive, Bidspotter, Invaluable, NumisBids, iCollector and LiveAuctionWorld simultaneously, alongside eBay, from one search box.
Does it cover sealed sets and minifigures separately?
Any keyword works, search a set number, theme name, or "minifigure" with a character name, and results return across every covered platform.
Can I get alerted the moment a new LEGO lot is listed?
Yes, save a search and get an email the moment a new lot matches it, across all covered platforms including eBay.
Is the extension safe?
It requests minimal permissions, cannot read your browsing history, only reads publicly visible auction listings, and never modifies pages or places bids. No account, no personal data.
