I think a few of these could be celtic copies of roman coins but I am unsure. What do you guys think?
These look like 4th or 5th century barbaric copies of Roman coinage to me, but I'm not an expert on these issues.
I would agree at first blush. I would guess first in the top row, and middle in second row are mint issues, the other limes issues. Its possible one of these two are also limes but hard to tell from such photos. I believe most limes coins were actually struck by either goths or germans, but on Ebay they are all listed as "celtic", right? I actually like limes coins, and have been meaning to get some. I like their artistry frequently.
These are all contemporary imitations of Roman bronze coins. The final two with the radiate crowns are imitating Tetricus and his son. The others are copying Constantinian bronzes. These are NOT CELTIC. They are in no way related to the Celts. Find spots indicate that they were struck within the boundaries of the empire. The 4th century imitations of the types you have were produced in Britain and Gaul, while the copies of the late 3rd century were produced primarily in Gaul, though they circulated quite widely in Britain. Properly, "limes" coins refer to a specific class of cast imitations of 2nd century bronze coins found along the Rhine border. The term "Limes denarius," referring to struck bronze copies of the silver denarius, is a fabrication of modern collectors. EDIT: the first coin is official, as Medoraman said. For more examples, check in my gallery under 'Imitations.' I've only completed proper cataloging for the Severan and earlier issues, unfortunately.
Thanks for the clarification. I knew limes were made on the boundary up by Cologne, but thought the term could be used for any contemporary imitation of the period. At least that is how I had seen the term used.
