Mechanics and Metals National Bank

The Mechanics and Metals National Bank (MMNB) was founded in 1810 in New York City as the Mechanics National Bank. In 1910 it merged with National Copper Bank (est. 1907 in New York), and took the Mechanics and Metals National Bank name. Between 1922 and 1925 it held a small ownership position in the Bank of Central and South America, together with several other New York banks. In 1926 MMNB consolidated with the Chase National Bank.

In 1911, a new and unrelated bank with the name, National Copper Bank, was founded in Salt Lake City.
