The 1942 Ten cents is part of a series of Winged liberty head (Mercury) dime coins struck from 1916-1945. Struck in Philadelphia and designated as a Business (MS) strike, this coin is made of 90% silver; 10% copper from a mintage of 205,410,000 struck. The 1942 Philly Mercury dime is a highly common coin in all circulated grades and is widely available through MS67, even with Full Bands details. Pieces grading higher are much scarcer and pose a little more challenge, particularly to registry set collectors looking for the highest-graded examples they can find.
