It looks like this to me: http://www.time-lines.co.uk/vitellius-dolphin-on-tripod-denarius-024646-37108-0.html But with some other things in the field near the tripod and dolphin. Any ideas?
Yes, it appears to be this coin (or some variation thereof): Vitellius AR Denarius. Rome, AD 69 RIC 109 A VITELLIVS GERMANICVS IMP AVG TR P, laureate head right / XV VIR SACR FAC, tripod, raven below, dolphin above. Added: Without clearer pictures it will be hard to discern any additional information about your coin.
Thanks everyone! I got it in an unidentified best-offer lot with another denarius (Antoninus Pius). Happy to have a coin of such colorful and briefly-reigning emperor, even if it is very worn.
