The Answer!

This is the coin. Reference RM4301 in the September edition of Spink's Numismatic Circular. Actually BEAT TRANQLITAS rather than BEATA TRANQVILLITAS and should come after 267 in RIC and after 355 in my new list for this period. The coin is to be expected and fits neatly into this series. These BEAT TRANQLITAS and BEATA TRANQVILLITAS can be quite confusing because of the number of minor varieties and the sometimes loose interpretations of the bust types by the engravers.
