The Classic Head cent is a type of U.S. coin that was minted from 1808 to 1814, featuring a design by engraver John Reich. The 1814 Classic Head cent, struck in Philadelphia, is particularly notable among collectors due to its historical significance and limited mintage. Four Dollar gold coins, also known as "Stella" coins, were produced in 1879 and 1880 as experimental pieces, consisting of a unique design intended for international trade. Collectors find value in these pieces due to their rarity and unique historical context within U.S. numismatics.
