Quadrans,
if I am correct, your system assigns the first position to the minting date in your
album "
Roman Republic". This would only
work for
Parthian tetras as both drachms and bronzes are not dated. In the following "
Twelve Caesars" albums you give all Gajus
Julius Caesar coins the 001 position, the Marc Anthony coins the 001a, etc., so you would be able to insert
new coins. Again, the system is not so easily transferable to
Parthian coins where the sequence, and even the names of rulers and dates are not established with certainty, in other words, things change. Orodes I. recently became Mithradates III., Vologases III. became Pakoros I., etc., and with the names the time of rule can change.
My old foolproof system was to move the coins around as needed with the sorting feature. This, for some reason, seems no longer possible.
Thanks, though, for your suggestions. You certainly have a magnificent
gallery!
