The numista page for the extremely common 100 drachmes is really unusual. Numista lists the 1990 date as "w/o inner circle" without having an entry for the opposing version, the "w/ inner circle"

The coin featuring the inner circle seems to be the scarcer version, as it realized 5 EUR on this auction listing below.

Also I have 10 of this coin and only one has the inner circle. I strongly suggest to add another entry for the 1990 date with the following text "w/ inner circle next to beaded border along the rim" as in its current form the entry doesn't make any sense without listing the other variety.
My coin is exactly like the one in the above link except it's in a bit worse grade.
Kind regards,
nucleus
