Did You Know?
Despite ups and downs in copper production and prices, the Quincy Mining Company on Michigan's Keweenaw Peninsula was able to pay its investors dividends nearly every year from 1862 to 1920, earning it the nickname "Old Reliable." The company closed in 1945 after nearly 100 years of operation.
