Urbana Money

According to a City of Urbana (IL) website, in 1933

When Illinois [closed] its  banks in the depths of the Great Depression,
the Urbana Association of Commerce [issued] "Urbana money," which [was] used
for a month and [kept] the local economy alive.

Apparently local merchants guaranteed that when the banks reopened, the "Urbana" money could be exchanged for the real thing.  My daughter learned about this in school. As she says, the money was orange and "looked like Monopoly money."
