On Wednesday, April 27th, workers digging a trench in Olivar del Zaudín Park in Tomares, a suburb of Seville, Spain, discovered a cache of clay jars nestled three feet under the surface. They alerted the Civil Guard who found there were 19 Roman-era amphorae crammed full of bronze coins from the late 3rd and early 4th century A.D. The number of coins has yet to be determined, but the total weight of them is a staggering 600 kilos (1,300 pounds).
Initial examination has found the coins were minted during the reigns of the emperors Maximian (r. 286-305) and Constantine (r. 306-337) and appear to be in brilliant uncirculated condition, with no signs of wear whatsoever. They are made of bronze but some of them show signs of having been silvered, ie, coated with a thin layer of silver totalling maybe four or five percent of the coin weight.
