Mints Across America

As a result of the Louisiana Purchase, the U.S. encompassed a much larger area than it had previously.  As the country expanded, so did its need for currency!  Did you know that during most of the 1800s and some of the 1900s the United States had a Mint facility in New Orleans, LA to help with the extra need for American coins?  It's true!  In fact, there were once Mint facilities all over the South and in other parts of our country as well.


Break your class into small groups and assign each group to a Mint Facility (these have been listed below).  Have each group research what was going on in the U.S. when these facilities were opened.  See if the students can find out why each facility was opened in its particular town.  Are there any similarities in the reasons for opening these branches?  What types of coins were produced at each site?  If the particular branch no longer exists, have your students find why it was closed.
