@Marsyas Mike for pointing out the existence of "Coins of British Association," discussed in this fascinating thread. Apparently, these were issued exclusively for use in Britain. I have two such coins, both middle bronzes of Faustina II minted under the authority of her father, Antoninus Pius: Faustina Jr, Augusta AD 147-175. Roman Æ as or dupondius, 11.41 g, 23.8 mm. Rome, AD 152-156. Obv: FAVSTINA AVG PII AVG FIL, bare-headed and draped bust, right. Rev: FELICITAS SC, Felicitas standing left, holding caduceus, left hand on hip.

Faustina Jr, under Antoninus Pius, 147-161. Roman orichalcum dupondius, 11.60 gm, 25.5 mm, 2 h Rome, AD 152-156.
