'Cirencester seems to me to have been a Mint Town, and an odd Coin of Carausius found there and given me lately by Mr Ballard of Campden seems to me to have been struck there. Mr Ballard hath carefully looked over his Roman Coins, which were found at Cirencester, and hath discovered a C upon the Ex[ergue] of three pieces (two of Allectus and one of Carausius) which he thinks a plain Demonstration of their being struck at Corinium. He can’t conceive to what other place it can be applied (Constantinople being built many years after) and, our Corinium being such a famous Roman city, for ought that he can see we may be positive that those pieces were there coined.'
