I am not an expert but as far as I am aware all Dritanniar errors are die 6 but not vice versa. It also appears that for this coin die 6 over a lower 6 is normal hence the loop under the die number. Also FYI these coins were for use in Cyprus.
Hopefully someone more knowledgeable will chip in, if not try the Predecimal Forum http://www.predecimal.com/forum/
