Automobile stock certificate auctions: historic car maker shares, searched at once

Automobile stock certificates capture the boom-and-bust history of the motor industry, shares in famous survivors like Rolls-Royce of America alongside dozens of long-forgotten makers such as Hupp Motor Car Corporation, the Comet Automobile Company and Woods Mobilette, each certificate a physical record of a company that once tried to make it in the auto industry.

Why automobile stock certificate lots get missed

Most buyers search for the cars themselves, not the paperwork behind the companies that made them, so a certificate from a historically significant or scarce automobile maker can go unnoticed in a general scripophily or ephemera lot.

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 car maker's name or "automobile stock certificate" 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 "automobile stock certificate": genuine Rolls-Royce of America, Hupp Motor Car and Comet Automobile Company certificates, 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 you collect

Save a search (a car maker's name, or "automobile stock certificate" 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 automobile stock certificate lots before adding the rest of the platforms via the extension.

Built for how automobile scripophily 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.
