Constantius I as Caesar, Argenteus with Legend Error. Argenteus; Constantius I as Caesar, Argenteus with Legend Error; 293-305 AD, Alexandria, Argenteus, 3.39g. Cf. RIC-12 (R5, on rev. officina letter A on l. rather than B on r. as on our coin). Obv: CONSTAN - TIVS CAES Head laureate r. Rx: VIRTVS - MILITAM (sic) Three-turreted camp gate, open, no doors, ALE in exergue, B=officina 2 in r. field. Ex CNG 105, 10 May 2017, lot 962 ("From the A.W. Collection") and ex Nomos 3, 10 May 2011, lot 235 ("From the Tetrarchy Collection, New York"). Apparently only the third known specimen of this exact argenteus, the other two being (a) Glendining, 23 April 1970, lot 376 = Gautier, Argentei d'Alexandrie, Rev. num. 1984, p. 141, no. 26, pl. XIV; and (b) CNG 57, 4 April 2001, lot 1410. All three of these specimens are from the same pair of dies, so all of them have the same misspelling MILITAM for MILITVM in the reverse legend, an error that Gautier also noticed on a second similar Alexandrian reverse die that was used for Galerius Caesar, Gautier's no. 27 and pl. XIV. A rare, interesting, and beautifully preserved coin, that reached a hammer price (without buyer's fee and postage) of 1900 Swiss francs ($2164) in the Nomos Sale of 2011.Iridescent toning. MS
