Finding Andrew Jackson on the Mall

We had a friend in Milwaukee who would scour the grounds of the park near our house with a metal detector. He raised a few dollars along the way. When we first moved to DC,  it was not at all uncommon to find money on the street. Given the amount of foot traffic and activities, it was especially lucrative on the Mall. Maybe because of the recession, folks seem to take the time to bend down more often when they see something that looks vaguely familiar. For whatever reason, there hasn't been much of anything to be found - until yesterday. You could say my husband hit the jack pot on his daily morning walk. Near the art museum was a folded bill tucked between two cars. When he opened it up, it turned out to be the picture of Andrew Jackson - a tidy sum. On the reverse side were two names and numbers - Tommy 13, and Diane 5. Do you suppose they were ages? Or the amount of money owed? There was no one else in sight, so what is one supposed to do? Bring it home of course. And he didn't even need a metal detector.
