This Magnentius is from the collection of Daniel Turner (1794- 1850) who was a War of 1812 veteran. At the age of 14, Turner started his Navy career. In 1813, he was promoted to Lieutenant and joined Oliver Perry’s squadron and commanded the brig Caledonia in the Battle of Lake Erie. On September 10, 1813, Turner’s suppressive fire for Perry's flagship Lawrence was so impressive and effective, that he earned a Congressional medal and a sword from the State of New York. He eventually commanded the USS Constitution in 1839 and served in the Navy until his sudden death in 1850. His collection, which included 292 Ancient Greek, Roman, medieval, and Islamic coins, stayed in his family until it was sold at auction in 2015.
