Thanks for dropping by and commenting on an admittedly minor detail. 
No signs of damage on the second coin (longer tail 9) However, the 9 on the first coin looks like it was hit at the end and flared slightly.
When I overlay both coins aligned to "DANMARK", the difference of the 9 is more obvious. Norseman might have some good thoughts here since the Copenhagen mint coined for Iceland during this time.
blowup of the both dates, where arrows show the endings of both 9:
