The coins were divided into four sections, each distin- 
guished by its peculiar type,—the Irish, the Anglo-Irish, the 
English, and the coins with three crowns on the reverse. 
In the first section the author pointed out the distinc- 
tions not previously recognised, between the groats and 
the pennies of Henry the Sixth, and those of Edward the 
Fourth, and showed that some of Edward’s coins have been 
heretofore erroneously appropriated to Henry the Sixth. 
In the second section proofs were adduced in corrobo- 
ration of Mr. Lindsay’s opinion concerning the date (1465) 
of the coins engraved in Snelling’s Supplement to Simon, 
Pl. I. Figs. 18, 19, and also that the coinage of 1467 was 
erroneously described by Simon as having “ a crown on one 
side,” instead of “ a face and crown.” Two unpublished and 
unique specimens of this coinage were described,—the 
double groat of Drogheda, the earliest coin known from this 
mint, in the cabinet of the Rev. Mr. Butler of Trim; and 
the half groat of Trim, in the cabinet of the Dean of St. Pa- 
trick’s. Some remarks were made on the difference between 
the Tower and the Troy pound, which have been frequently 
confounded by the writers on Irish coins. 
The coins with the King’s head on the obverse, and a 
rose, instead of pellets, in the centre of the reverse, Dr. 
Smith considers to have been coined in 1470; and he sup- 
ported his opinion by reference to the Act of the first of 
Richard the Third, and by other evidence. 
In the third section, two unpublished and unique coins 
were described,—the half groat of Drogheda, in the Dean of 
St. Patrick’s cabinet ; and the half groat of Trim, in that of the 
Rey. Mr. Butler ;—and some reasons were assigned to show 
that the letter G, which is found on most of the groats of 
Drogheda, Dublin, and Waterford, was the initial of Ger- 
myn Lynch, the master of the mint. 
In the fourth section Dr. Smith remarked that Sir James 
Ware, or the writers since his time, had not given any ex-
