Dean, it sounds now as if what you primarily wanted was a kind of conjectural appraisal for your coin, not a bad thing to want, but less useful than learning to gauge for yourself what makes some coins more valuable than others. As I noted at first, your own coin's
reverse type is unlisted for
Sev.
Alexander but is tolerably common for other rulers; if you want to gauge what your coin's worth, you should probably compare it to other small semi-scarce
Roman provincials in more or less similar condition. The point then wouldn't be to do more research on this particular
Sev. Al.
reverse -- we've researched it already -- but to see what small, semi-scarce
Roman provincials habitually bring. If you went to the
Nicomedia page on
Wildwindshttp://wildwinds.com/coins/greece/bithynia/nicomedia/t.htmlyou would locate an entry for a
Maximus Serapis in quite similar condition to yours; if you then did the
Isegrim search from Reply #3, you would see that the
Maximus issue is also quite
rare, only one specimen listed in
Isegrim, and a right-facing specimen at that. But the specimen on
Wildwinds was bought for just $8, not that it couldn't bring more than that, but that it clearly wasn't a treasure. So what your coin might reasonably bring is somewhere between $8 and $40.
