1842 Liberty Half Eagle. Small Letters. AU Details--Tooled (PCGS).;This 1842 Small Letters half eagle is sharply struck with bright, somewhat chrome-like surfaces. Speckles of russet are evident here and there on the reverse, but the overall appearance is vivid green-gold. Although not quite as rare as its Large Date counterpart, the 1842 Small Date is one of the scarcer Philadelphia Mint half eagles from the early 1840s. The mintage of 27,578 includes both Small Date and Large Date coins.;
