To celebrate Coco's 125th Bday, Karl Lagerfeld has designed a 5euro coin, shown above. With Coco on one side and the iconic quilting on the other. The gold version costs 5900 euros and only 99 of them were made; the silver version costs 45 euros and there were 11,900 of them made. These coins go on sale in December.
Not sure where to buy them, but it would make a neat gift for the fashionista in your life, I wonder what they would be worth and if Karl has ever done this before. I will get back to you!
