Yes the 2 is the code for the
legend on your coin. Your ex. does not have the dots. And that is okay
per RIC as it lists the possible ex. as KAA to KA
D or
officina 1 to 4 which would include
G from your coin as the third
officina as well as the KA.
G. example. For this series of coins
RIC does not date them.
RIC dates some but not all of the coins that are listed.
I was glad to send you the scan of the
part of the page that your coin showed up on.
Hope that you can see that
RIC is a LOT of coding from that scan.
