Year lines are locked for this coin. Clicking on “modify or add data to this page” is useless. The correct way to ask for a new year line is to request it in this forum (as the OP did) with the message tag of “requesting the modification of a coin in the catalogue.”
No need here: I sent the request to the referee, now waiting for review.
