At the moment the Belgian 2 centime piece from 1833 - 1865 is listed under KM# 4 - How would one split it into KM 4.1, 4.2, 4.3, 4.4, and 4.2a without duplicating (or erasing the work that has gone into) the entry that is there?
The best way to do is to specify the different versions in the coin description. Then the specific KM number would be written as a commentary for each issue.
Tell me wich years KM#4.1, 4.2, 4.3, 4.4, and 4.2a were struck and what are their specificities, and I will do the modifications.
