The US Postal Savings System let depositors save through their local post office from 1911 until 1966, and the certificates of deposit it issued, most commonly the Series of 1939 in denominations from one to five hundred dollars, are collected today for their engraved eagle vignette design, the issuing post office town, and whether the certificate was ever redeemed. Genuine unredeemed high-denomination certificates from smaller towns command the strongest premiums.
General paper ephemera and banknote sellers often describe these simply as "old US certificate" or "government document" without naming the Postal Savings System, so a genuine unredeemed five hundred dollar certificate from a scarce town can sit unnoticed in a listing that never surfaces in a single-site browse.
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 "postal savings certificate," "postal savings system," a denomination, or a town name 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 "postal savings certificate": genuine Series of 1939 certificates of deposit in various denominations and towns, 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.
Save a search (a denomination, a town name, or "postal savings 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.
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 postal savings certificate lots before adding the rest of the platforms via the extension.
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.
