On arriving home, my in-laws had opened the cans and found that they had a problem. Over the intervening years, the cans had corroded and begun to leak. Water, containing minerals from the dirt, as well as chemicals from fertilizers and plant food, had gotten onto the bills and stained them considerably. In this condition, they could not possibly have been circulated without arousing a lot of questions that would be hard to answer.

The solution was to literally launder the money—to soak it in a mixture of bleach and mild detergent to try to get as much of the stains out as possible. This succeeded in getting most of the stains out, but it also took out some of the dyes in the ink, and left the bills looking strange and discolored. Passing them in stores would still raise some eyebrows.
