Nice find. A question. Limes means an official or psuedo-official denarius paid to the military serving on the extreme fringes of the Empire, or is it just a name given to imitations from the same areas? I just briefly tried looking them up as I am still quite new to ancient collecting and the results were conflicting. Thanks for any help
The limesfalsa first described a century ago by Kubitschek were lightweight copies of imperial aes (sestertii, dupondii and ases, never denarii) found near the old limes in Pannonia. Kubitschek postulated that this assemblage represented a quasi-official emergency or military coinage. Since that time, however, similar material has turned up in various locations. Kubitschek's perceived association with the limes thus proved illusory. George Boon, who has written on the topic, suggests instead the term "lightweights". The majority opinion is that they are simple contemporary counterfeits, though one still finds occasional claims to the contrary. The term "limes denarius" is believed to have originated on eBay in the early 2000s as a misinterpretation of limesfalsa, itself already obsolete. "Limes denarius" is primarily a marketing term, not typically found in the literature. This doesn't mean that they aren't interesting or collectable, only that they are best understood in the broader context of contemporary counterfeits.
