This note will take another look at the Stuart hammered silver coins that have been countermarked with a cartouche containing various Roman numerals; III, VI, VII and VII above a horizontal I. The five previously published specimens are presented and discussed along with a further piece that might be attributed to this group. The weights of the pieces are found to correlate with the numeral in the countermark, but no plausible explanation for the issue has been found. All of the pieces should be considered as unsolved until new evidence appears.
