That Time the Government Burned $200 Million of Hawaii’s Cash

The government rounded up U.S. paper currency in Hawaii so it would’t fall into enemy hands.

In 1942, after the attack on Pearl Harbor, the American government became worried about what would happen if Japan invaded Hawaii. Specifically, officials were concerned about all of the U.S. money on the islands. If the Imperial Army invaded and grabbed all the cash, how could the government flag or demonetize those bills? After all, the money would be indistinguishable from all the other U.S. money in circulation.

To hedge against that situation, the government did something unusual: they recalled all of the paper money in the territory, asking the people and businesses to trade in their money for freshly printed bills that looked fairly standard except for the word Hawaii stamped across them. The U.S. government also issued strict rules about how much money anyone in Hawaii could carry: individuals could have no more than $200 (about $3740 in 2024 dollars) in cash, while businesses were capped at $500 ($9350 today).

But what about all the money they’d just collected in the recall—the $200 million of regular currency rounded up on the islands? Instead of putting it into circulation, or stockpiling it somewhere, the government decided the simplest solution was simply to burn it. Of course, this ended up being its own hassle. According to The Numismatist, officials started by trying to incinerate the massive piles of money at a crematorium in Honolulu. But when they couldn’t burn the cash fast enough, they had to commandeer some furnaces at a sugar mill in Oahu to get the job done.

By October of 1944, the U.S. no longer felt the threat from Japan, and they took the emergency bills out of circulation, allowing normal currency to re-enter Hawaii. The Treasury pushed some of the overprint bills to other islands in the Pacific. Today, very few of the Hawaii bills are still in circulation, but if you find one, hold on to it. Depending on its denomination and series, a Hawaii overprint bill at auction can sell for a few thousands dollars up to $52,000 or more.
