As America's oldest coin auction house, Stack's Bowers has had the privilege of auctioning many of the rarest coins and most valuable collections ever assembled. Now, 83 years after we held our first coin auction, our tradition of success carries forward into the 21st century as we continue to sell rare coins and currency for collectors across the world. Our knowledgeable staff offer unsurpassed expertise in all areas of numismatics, as well as commitment to excellent personal service.
