Numismatics—acquiring old coins—outperforms other investments

BEHIND the heavily fortified door of Stack’s Bowers, a gallery of rare coins in New York, smiling salesmen show off their precious wares neatly displayed in pristine glass cabinets. To the untutored eye, it looks like pocket change. Numismatists, who study the history and art of old money, see well-preserved coins as aesthetic masterpieces worth many times their face value. At an auction organised by Stack’s Bowers on March 31st, an American cent from 1793 (pictured) sold for $940,000, becoming the costliest penny ever.
