I have seen a hundred worse uses of $59 posted here in the last year or so. We all would like better for less but this seems like a decent coin not all that much more than would seem good these days.
That Crispus is very interesting even to those who are well aware of the type and the likelyhood of it being a unofficial issue fits so well into unofficial rarities minted likely on the Rhine and/or in Gaul proper based on types from the 310s and 320s. I have a pet theory about these coins that I sometimes dwell upon when I see such coins, a (very) little about it I have mentioned here.
I like the small Crispus coin for that range is a very cool type, the best for me is the Marcus Aurelius As. Congrats !!
