US banknote auctions: large size notes, national currency and star notes, searched at once

American paper money runs from oversized 19th century large size notes, through national bank notes issued by thousands of individually chartered banks, to gold and silver certificates and modern star note replacements, each a distinct collecting field with its own premiums for scarce charter numbers, low serials, or printing varieties. The same search box that finds Bank of England notes finds these just as easily.

Why US banknote lots get missed

National bank notes in particular are tied to a specific chartered bank and town, so a note's true rarity depends on how many that charter issued and how many survive, detail that a general seller listing "old US currency" from an estate rarely knows or mentions. These unresearched lots are exactly where undervalued notes hide.

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 charter number, a state, "large size note," "national currency," "silver certificate" or "US banknote" 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 "US banknote": from a genuine 2013 two dollar note to novelty million-dollar and gold foil sets, filtered by platform in tabs so you can skip the novelty items and go straight to genuine currency.

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 notes that don't come up often

Scarce charter numbers and low serials are infrequent, so save a search (a state, a bank name, or "US banknote" 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 US banknote lots before adding the rest of the platforms via the extension.
