Attribution Help: Radiate, Possibly Tacitus/Clementia Temp

Seems good to me, that would be appropriate for the coin.

Looks good to me. When it gets here, I'll get photos that are decent, and check the mark after XXI. Looks like the reverse might be double struck below the denomination (or that could also just be encrustation.)

Maybe he pressed a captured Goth into service as a die-engraver...

edit: rest of the lot:

Maximianus / Concordia Mi-litvm (a keeper, probably, great obv patina)

Maximianus / Concordia Militvm (not so much...)

Gallienus / Felici Aet (ok! keeper for sure, I like interesting Gal reverses)

Trajan Decius / Dacia (ok? pretty sure, but reverse is questionable)

Licinius II/Iovi Cons-ervatori (resoundingly "meh", unless it's an interesting mint!)

Valentinian (2/3?) / Reparatio Reipvb (Thessalonica - SMTES) - another "meh" coin, obverse is great, reverse is weak)

..and one more I don't want to post yet until I get to look at it in hand

Now that's an obscure reference, had to look that one up!

Oh, I love esoteric references!

Nothing like going down the Google rabbit-hole for a brief search that turns into 30 minutes of exploring Colombian artists..

Sure looks very close. thanks maridvnvm :)
