Hi!
This I want to add:
These coins are called Limesdenarii or Limesfalsa (Sing. Limesfalsum). This second term was created by G.Elmer 1933, important research can be found in (1) George C.
Boon, Coins and the Archaeologist,
Seaby, 1988.
Historically it was probably the coinage of the
Roman frontier troops along the
Limes, at the Northern
border of the Empire, which have big trade with the local tribes. Formerly they were looked at as couriosities, most of them found in
England. Nowadays they are relative frequent from the states in Eastern Europe. The specimens found until now seem to be
cast and not struck. There is no silver in the
alloy, a possible
fine silver layer is gone. The coins are from the time of
Trajan until the reign of
Maximinus. Most of them are from the
Severan emperors.
Wether they are
counterfeits or official issues for the frontier soldiers is not yet cleared. We have not enough knowledge. The time difference to the official issues is sometimes more than 10 years. So f.e. coins of
Septimius Severus were found with the
reverse of
Alexander Severus. This would be a sign for an unofficial product.
