Yes, We Have No $20 Bananas

From AP:

An ordinary fruit sticker that mysteriously ended up on a $20 bill could spur currency collectors to bid up to 1,000 times the bill's face value at an auction Friday.

The flawed bill bears a red, green and yellow Del Monte sticker next to Andrew Jackson's portrait. The bill originated at a U.S. Treasury Department printing facility in Fort Worth, but how the fruit tag found its way onto the greenback is unknown.

In the case of the banana note, the seal and the serial number are both printed on top of the Del Monte sticker, meaning the fruit tag must have found its way onto the bill midway through the process, he said.

The note is all the more rare because the Bureau of Printing and Engraving diligently inspects and destroys flawed currency before it escapes the plant, Bradford said.

After hearing about this I looked in my wallet and found this $10 bill. In place of "IN GOD WE TRUST" it says "IMPEACH BUSH". Oh, those whimsical engravers at the Bureau!!! Wonder how much it would be worth at auction.....
