Book excerpt: Over 75,000 coins have been found during excavations at the Agora, many minted in the city but others brought from Athens's far-flung commercial contacts. In addition to the mostly bronze and copper coins themselves, a building that may have served as the Athenian mint is described in this booklet. After describing the physical techniques of production, the author takes a chronological approach and includes numerous black and white photographs, making this concise guide a useful aid to the identification of lower-value Greek and Roman coinage.
