Spencer Miller

Director of Ancient Coins

Spencer Miller, currently Treasure Town’s Director of Ancient Coins, oversees our purchases of ancient Greek, Roman, and Byzantine coins and prepares them for our auctions. Spencer currently attends Tufts University in Boston, where he is pursuing a major in history and minor in political science. These days, he is busy conducting research with the chair of the Classics Department on excavated Roman, Vandalic, and Byzantine coins from the Canadian UNESCO dig at Carthage. A numismatist since the age of five, Spencer transitioned from U.S. to ancient coins at the age of 14. In addition to working for Heritage Auctions in Dallas, he recently founded a company that buys and sells higher-value ancients through auction houses and private sales in Europe and the U.S., and he is excited to bring his knowledge of the market and ancient history to Treasure Town. Spencer’s specialties within ancient coins are early electrum, Hellenistic, and Byzantine issues; his primary goal with Treasure Town is to provide quality material with tangible historical importance for each sale. Spencer’s 6+ years of experience in the ancients field have given him a keen eye for authenticity, which he prides himself on, as well as eye appeal and rarity.
