This one has a star-cross-cross arrangement, which I at first figured was SB 87. However, while pulling up examples online, I found another type, SB 86, which was in neither Wildwinds nor Labrum. The difference between SB 86 and SB 87 is an additional cross on the obverse. While researching the Obverse Cross Type, I came across examples in auctions. This one from Harlan J. Berk has a large and spectacular obverse cross: https://www.numisbids.com/n.php?p=lot&sid=2037&lot=310 Some of them had smaller obverse crosses. This one looks like mine - the cross is small, seeming a part of the headgear: https://www.coinarchives.com/a/lotv...&Lot=325&Val=afbdb6656d92c3ce70feb0fab01424d1 Here is mine - I think I can see an obverse cross: Justin I Æ Follis n.d. (518-527 A.D.) Nicomedia Mint DN IVSTINVS PP AVG, pearl-diademed, draped, and cuirassed bust right, cross above / Large M, cross above, star left, cross right, Officina A below, NIKM in exergue. SB 86; Berk 73; MIB 39. (15.31 grams / 28 mm) Close-up view: Maybe I'm deluding myself. I'm guessing there are other Justin I variations from Nicomedia; labrum's SB numbers run 83, 87 and 88, leading me to believe there are other variations in between (I don't have Sear's Byzantine book, where the SB comes from). These appear to be a bit scarce, and all of them I found were from Officina A. http://labarum.info/lbr/index.php?s...er=Justin+I&sf_mint=Nicomedia&sf_denom=follis Here is SB 83, star-cross-star reverse, no obverse cross: Justin I Æ Follis (518-527 A.D.) Nicomedia Mint DN IVSTINVS PP AVG, pearl-diademed, draped, and cuirassed bust right / Large M, cross above, star left, star right, Officina B below, NIKM in exergue. SB 83; DOC 28. (17.77 grams / 29 mm) I'm sure there are scads of CT Justin I's out there from Nicomedia. Maybe worth another look to see if you have one of the scarcer variations?
