This article focuses on two early medieval imitative coins found in Bohemia (one in the vicinity of Hradec Králové / Königgrätz in 1931; the other in Prague–Klánovice in 2016). The coins were probably struck in 1010–1015, and on the obverse imitate the Saxon denarii of the Otto-Adelheid type with the letters O-D-D-O in the arms of the cross. On the reverse, there is a church with the letters •VIDV, imitating Bavarian or Bohemian denarii from the second half of the 10th century. The location of most of the finds of these denarii in central Europe, including both coins found in Bohemia, indicates their Polish origin. Nevertheless, their issuer remains uncertain.
