the number of leaves do not matter...these are struck with hand engraved dies and there will always be slight differences. Your coin is Claudius II and the reverse looks like APOLLI CONS though there is also an APOLLINI CONS and APOLLINI P CONS; but your reverse legend doesn't seem long enough. So your coin is RIC V Rome 21.
https://en.numista.com/290108The numista example has H in right field; while yours has M (possibly N; which is not listed for this issue, but is in a preceding issue. Maybe just an error in RIC and it should be listed as N though) in the exergue. Other possibilities listed are A and H in exergue. These are all the same listing, just different workshops.
