A $1,000 U.S. note, printed in 1890, garnered nearly 2.3 million dollars from an art and rare currency collector in Dallas, Texas. The bill is know as a “Grand Watermelon” because of the stripe pattern used on the zeros. A portrait of Union Major General George G. Meade is on the front.

this is why some people collect–the potential for a pay-off like this, even tho’ it’s extremely rare.
I wonder what an 1890 $1,000 bill would be worth today if you adjusted for inflation…
