Americans forgot to cash in savings bonds worth billions of dollars

American savings bonds have been a popular gift for decades — parents and grandparents bought them for kids, expecting them to cash the bonds in years later once they fully matured.

The twist: an enormous number of these bonds were never redeemed — owners forgot about them, lost the paper certificates, or died without ever telling their heirs the bonds existed, leaving the money waiting, unclaimed, for years.

Some of these bonds have already stopped earning interest entirely, having hit their maximum maturity period — yet the face value still sits there waiting to be claimed, with no expiration date, so in theory someone could still come forward for it at any time.

The stakes: this reveals a fairly non-obvious paradox of the financial system — money formally belonging to specific living or deceased citizens can sit inside the government system for years, doing absolutely nothing, simply because nobody remembers to go get it.
