According to a Japanese newspaper, eight people are out more than $1.25 million. They were duped into buying supposedly rare U.S. million-dollar bills from the 1920's. But the ‘million notes’ are fakes. The news reports say three of the bilked investors have had to file for bankruptcy. The man who promised them huge returns has disappeared with their real money.
The largest denomination bill ever produced by the U.S. treasury was a 100-thousand-dollar note in the mid 1930's.
