Milwaukee’s Exposition Building, featured on the reverse of the official so-called dollar, SH 4–61, opened in 1881. Regarded as the cities crown jewel at the time, the Queen Anne style brick building was constructed entirely with private funds. One so-called dollar was struck for this exposition. The details are cataloged in my 2023 book So-Called Dollars Volume I: United States Expositions. Click on the “View All” link below to see them.
