Three coins of Marcianopolis struck with the same obverse die but with different reverse types entirely: Post your die-matches or anything you feel is relevant!
Another superduper neato thing about Provincials Great set, RC!! I don't have any such examples within my own collection but @Ancient Aussie has a fantastic architectural reverse with the same obverse die as my coin: MOESIA INFERIOR. Nikopolis ad Istrum Elagabalus , CE 218-222 AE 26 mm, 11.1 gm Obv: AYT K M AYP ANTΩNEINOC. Laureate, draped and cuirassed bust right Rev: VΠ NOBIOV POVΦOV NIKOΠOΛITΩN ΠPOC ICTPON. River-god reclining right, holding branch; prow at side Ref: Varbanov 4055 ex Falter Collection, Nature Gods
There is an old(ish) thread where I illustrate 5 different reverses with the same obverse die in my own collection and @dougsmit illustrates another reverse type in his own. https://www.cointalk.com/threads/my-latest-sept-sev-imp-ca-cos-ii.296314/#post-2738253 It is nowhere near the largest number of obverse dies I have matched to different reverse dies.
Great coins RC, I don't have any die matches but I think this is the one TIF is referring to.Moesia Inferior. Nicopolis. Elagabel. (218 - 222). Ae. AMNG I 1982
My personal best is six but I believe I have seen thirteen different from a different obverse of Emesa. I pretty much stopped looking for these since they have become popular and more costly.
Here is another post about my die links. I now know of 14 reverse dies paired with this obverse die of which I have 8. https://www.cointalk.com/threads/my-last-coin-purchase-of-2015.272355/
