What is a Two dollar bill with yellow ink?

A 1963 2 dollar bill with yellow ink is considered very rare since it was an ink error. It escaped the quality control of the US mint and should not have been released. 1963 2 dollar bills were printed with red ink. It would be worth a premium price to a collector the better the condition, the higher the value.

????There are no known reports of ink errors on 1963 US $2 bills. And more importantly, the US Mint DOES NOT MAKE PAPER MONEY, it only strikes coins! ALL US paper money is produced by the Bureau of Engraving and Printing. The last time yellow ink was used on US bills was during WWII to create special bills for use in war zones.

More likely, the bill has simply been exposed to something (bleach, laundry detergent, etc.) that leached some of the color out of the seals.
