Sounds like it would be a good idea to visit the Omaha Durham Museum if you live close by or visiting Omaha:

Rosa Gumataotao Rios was in familiar territory at Omaha’s Durham Museum on Thursday evening, namely the collection of historic coins, currency and other rarities amassed by early Omaha businessman Byron Reed.

After all, her own name is printed on millions of U.S. bills as the Treasurer of the United States, overseeing the U.S. Mint, the Bureau of Printing and Engraving and the nation’s gold stash at Fort Knox, Kentucky.

She gasped at some of the rare coins, marveled at historical documents and issued the occasional “Wow!” as museum director Christi Janssen and curator Carrie Meyer showed off some of the museum’s treasures. “It’s an amazing collection,” Rios said. “I’m overwhelmed.”
