The earliest of coins attributed to the Coriosolites, they are the sole design group in Class VI. Very few of these coins survive so it is impossible to be very certain of any intended weight or alloy standard. There are two threads of design evolution within this group; one leads to Group B and becomes extinct, the other leads to Group C and thence to the rest of Series X. This could be due to the engraver of Group B ceasing production, or it could mean that the dies should be arranged: Early VI (Aa) - Early V (B) - Later VI (Ab) - Later V (C). I suspect the latter of the two possibilities, but more evidence is needed. This could demonstrate the folly of arbitrary classification based on one or two elements.
A curious feature of these coins is that of 100 recorded Coriosolite coins from Britain (excluding Jersey), 10 have been Group A. This is a much higher percentage than find proportions from elsewhere: The largest number of Group A coins found in a single hoard are the 19 specimens from Jersey 9 ( La Marquanderie), this hoard contained over nine thousand coins. The Trébry hoard from France contained only five Group A coins out of over seventeen hundred specimens.
