The coins of Lilavati, Dhammasoka Deva, and Sahasa 
Malla corrode green too, but a very much darker green. 
The second trio do not corrode nearly so much as the first 
trio, and it is easier to obtain good specimens. 
While among a hundred coins of any of the first trio it 
would be hard to find half a dozen specimens not coated with 
verdigris, among a similar number of the second trio there 
would probably be sixty or seventy clean, undamaged speci- 
mens of a very dark, nearly black colour. 
(iv.) General workmanship, — The coins of Vijaya Bahu 
and Bhuvaneka Bahu are of rougher finish than those of the 
other four rulers, and show infinitely more careless work- • 
manship. They are not so perfectly rounded, nor so uniform 
in character. And fifty of either of these varieties would 
probably produce more variations than five thousand of 
those of any other king. Whether owing to the rough-cut 
dies or to the metal being softer, the percentage of good 
specimens of these two kinds is very small compared to the 
others. Therein they differ from Parakrama Bahu's issue. 
It will be noticed that these two varieties partake more 
of the character of Parakrama Bahu's coins than of the 
issues intervening between those and Bhuvaneka Bahu. 
But they differ so very much in several ways that they 
really form a class by themselves. 
They are ill-rounded and extraordinarily varied in type. 
Parakrama Bahu's are well cut, and vary very little. 
Taking into consideration all these points, in which the 
two vary from the four but resemble each other, it does not 
seem likely that the coins represent the first king of the 
name Vijaya Bahu. 
If they do belong to Vijaya Bahu I., the chronological 
order is thus : — 
Vijaya Bahu I., 1065-1120 A.D. 
Parakrama Bahu I., 1164-1197 A.D. 
Sahasa Malla, 1200-1202 A.D. 
Lilavati, 1208, 1209, and 1211 A.D. 
Dhammasoka Deva, 1208-1209 A.D. 
Bhuvaneka Bahu I., 1277-1288 A.D.
