As you see it looks that this coin doesn't have catalogue number. But it has. There are only four lines for description but here we need five. You can see that only part of additional text is under picture of coin - that is catalogue number.
You can see similar behavion for all coins that have larger description than four lines.
Could admins fix that?
Or the Commemorative text doesn't have to be so long. It could be i.e. 150th Anniversary Birth of Akseli Gallen-Kallela or even 150th Anniversary Akseli Gallen-Kallela. The "of the[birth of] artist" part is really unnecessary, if you ask me. Of course birth of could stay, since sometimes a person's death is commemorated.
