Andres => here are the CNG seller notes on my humble example ... Roman Republic Post Reform Æ Semis (Anonymous) Circa 88 BC (?) Rome mint Diameter: 21mm Weight: 5.96 grams Obverse: Laureate head of Jupiter right; S (mark of value) behind Reverse: Prow of galley right; S (mark of value) above; to right, dolphin downward, ROMA in exergue Reference: Crawford –; Sydenham –; BMCRR II, p. 589, 10 Other: 2h, Near VF, dark green patina. Rare From the British Museum catalog: “The date of issue of this coin is doubtful. It is of the semiuncial standard, and corresponds in work and style to similar pieces also with symbols which Count de Salis has assigned to B.C. 88, i.e., after the passing of the Lex Papiria ...” Ummm, I can't quite recall who made the following comment ... but it was made (thanks for the input, coin-gang => I like you guys) Edit: I think Steve's dolphin semis is unofficial. See #66 of Crawford's "Unofficial imitations and small change under the Roman Republic" AIIN 29, 1982. The orientation of the dolphin is reversed from Crawford's official Dolphin Series 80 (for which Crawford lists no semis). The dolphin orientation matches the unnoficial semis #66 from the above article. Hey => ummm, I'm certainly not lookin' for more "likes" ... => I'm just tryin' to answer my coin-friend's question I hope that you're having a sweet Hump-day!!
Never seen one with a dolphin in front of the bow , very natural though, Dolphins like to swim in front of ships. Wheater its struck unofficial somewhere in Italy , Sicily or even Spain no idear, but I agree with the Count ,the weight corresponds with 88 BC beautifull coin, congrats.
