I don't know how they did it, but an eagle-eyed Walmart cashier in Lexington, Kentucky somehow managed to foil Michael Anthony Fuller's attempt to pay for a purchase with a $US1 million bill he made.
Maybe he didn't get the watermarks exactly right? And it's not like Fuller attempted to buy a million dollars worth of merchandise. Instead, he got to the checkout with a vacuum, a microwave, and a few other items totaling just $US476.
The store called the police, and later Fuller was charged with two felonies: attempting to obtain property by false pretense, and uttering a forged instrument. Unknown to him, in 1969 the US government had discontinued the $US500, $US1,000, $US5,000, and $US10,000 bills. And the largest bill ever produced was a $US100,000 note used by Federal Reserve Banks.
