Ancient Roman and Greek Coins

There can't be many around--aren't they all in museums?
Actually, there are many around. If you live in the United States it is hard to realize how common it is to dig up really old archeological artifacts in England, France, Spain, Italy, Greece, Bulgaria, Serbia, Turkey, Syria, Israel, Jordan, Lebanon, Egypt, Iraq, Iran, Tunisia, Libya and other a dozen other countries where ancient coins are found. If you were a collector in England, you would see ancient coins for sale in every coin shop because they find them in the ground--sometime in hoards of thousands together. Museums get first pick (and pay market value in England, but not other countries), but most finds are duplicates of types already in the museums, so the coins go on the market.Nineteen amphora full of coins found in 2016 in Sevilla, Spain. Workmen were doing routine work on water lines under a street when they stumbled across 80,000 Roman coins. This is not an unusual occurrence. Next is the "Frome Hoard" found in England in 2010 in the middle of nowhere (not a previously known archaeological site) by a metal detectorist.
