I've never seen one for sale, either at auction or fixed price. https://www.artic.edu/artworks/36645/solidus-coin-of-leontius Above link shows one at the Art Institute of Chicago...pic below
That is the common Leontius II . I meant Leontius I 484-88 Usurper time of Zeno. He was captured in 488 and ordered beheaded by Zeno. I have the L. II
Sorry folks. I googled Leontius I solidus and that link was the first result, and the collection doesn't specify whether it is Leontius I or II.
Not only in gold but in bronze. The only one that maybe, could be, there's a possibility is the monogram. Here's mine (sorry, old photo): It's basically a Leo with a bar at the top of the E. What's interesting is that I've seen probably 10 of these and not a single one has a legible obverse legend. The other one is the piece that Sear warns us about, the Leontius ae4 type. I found mine in an uncleaned lot. Obv: DN LEON-TIVS P AVG; bust right Rev: VICTO (RIA AVG); Two Victories facing each holding a wreath Someone obviously put a lot of effort into this 12mm coin but I agree with Sear, it's likely not genuine.
