Archaeologists uncovered an estimated 100,000 ancient coins, some of which are of Chinese origin and are more than 2,000 years old. The coins were tied together in bundles with a straw rope passed through a hole in the middle. The haul was unearthed in the Sojamachi district of Maebashi City, Gunma Prefecture, at a construction site of a factory. Only a small sample of the coins could be analyzed for dating, and the oldest was believed to be a Ban Liang coin from 175 B.C. Those were the first coins minted in a unified China.

So far, 334 of the coins have been examined. At least 44 types were confirmed, ranging from those made in 175 B.C. to as recent as 1265. One confirmed Ban Liang coin had a diameter of 2.3 centimetres and was 1 millimetre thick. The square hole in the middle measured 7 millimetres on each side. The characters for "Ban" and "Liang" were engraved on the surface. Because the newest coin dates to 1265, the trove is believed to have been buried during the Kamakura Period (1185-1333). However, the date of burial could change after more coins are analyzed. The site where the coins were dug up has a large number of relics, leading experts to surmise it was a central part of Kozuke province, the predecessor to Gunma Prefecture, from around the time of the Kofun (burial mounds) Period between the late third century to the late seventh century.
