A set of 867 Ibero-Roman coins stolen from a collector in Madrid nearly a year ago has been recovered, the Spanish National Police said Wednesday.

The set includes a one-of-a-king coin stolen by the burglars, police said.

The Imperial Roman coins date from the 1st century B.C. to the 1st century and their historical valuable cannot be estimated, the National Police said in a statement.

National Police director Ignacio Cosido congratulated the officers who recovered the coins and displayed the coins for reporters. EFE
