I wonder if more is known about the limes falsa by now. At the beginning of this year I bought a lot of limes falsa through the Numismatic Naumann auction. Bought this lot because it contains very sharp images. So hit with fairly new dies. I am amazed that some coins are as heavy as silver denarius. While there are also some that are much lighter. This makes it clear that these are made of a different type of material. I first post the lightest and then some of the sharpest.

If I recall correctly, the term limes falsa is used for cast copies - either base metal cast copies of denarii or casts of large copper-alloy denominations. If struck, but not official, yours would be more of a unofficial or imitative copy than a limes falsa. SC
Originally, the term limesfalsa refered to cast copies of early imperial bronze (only), finds of which appeared to be concentrated along the imperial borders (limes). In the century since the term was coined, it has become apparent that cast copies of the limesfalsa type are more widely distributed than originally thought and the notion originally postulated of a quasi-official border coinage has been abandoned. They are now classed with other contemporary counterfeits. The term "limes denarius" is thought to have originated on eBay (!) in it's early years, likely as a misunderstanding of limesfalsa. The term has since taken hold in the trade but not in the literature. As noted above, even when the notion of limesfalsa was current, it never included copies of denarii. Debased casts of denarii are found widely in areas where imperial denarii circulated. Due to the debasement of official coins, high-tin bronze must have looked "white" enough, at least when the copies were newly cast. Their production was likely stimulated by the relatively high intrinsic value of the denarius relative to the antoninianus, which was tariffed at 2 denarii but never contained more than the equivalent of 1-1/2 denarii in silver. Odds are, the op coins are very good casts. Struck counterfeits would be unusual for the early to mid 3rd century.
