Valerian I, (Publius Licinius Valerianus), AD 253-260. Antioch mint; silver Antoninianus. Obv.: IMP C P LIC VALERIANVS P F AVG; Radiate draped cuirassed bust, right. Rev.: RESTITVT ORIENTIS; Valerian standing, receiving wreath from Orient. Diam.: 21 mm. Weight: 3.3 gr. Attrib.: Cohen 189. RIC 287, page 60. (Scarce.) Perhaps it goes without saying, but in this period (the start of the Crisis of the Third Century) the silver content really took a nosedive. Unfortunately, the silver content was so low that not many nice examples are extant -- and several of those that do remain have surface/metal issues.
