A hobbyist with a metal detector has found a cache of ancient Celtic and Germanic coins in a cornfield in the southern city of Maastricht. The city says the trove of 39 gold and 70 silver coins are dated to the middle of the first century B.C. The hobbyist, Paul Curfs, 47, found several coins this spring and called attention to the find, which eventually led to an archaeological investigation by Amsterdam’s Free University. ..

Nico Roymans, the archaeologist who led the academic investigation of the find, believes the gold coins in the cache were minted by a tribe called the Eburones that Caesar claimed to have wiped out in 53 B.C. after they conspired with other groups in an attack that killed 6,000 Roman soldiers.

The Eburones “put up strong resistance to Caesar’s journeys of conquest,” Roymans said.

The silver coins were made by tribes further to the north – possible evidence of cooperation against Caesar, he said.

Both coin types have triple spirals on the front, a common Celtic symbol.
