Certainly not because it is old. Usually I don't treat my lenses with
toothpaste ;-)
I did it in the past with some two lenses that had a "dull" coating on the
front lens. On an other occasion I tried to clean an old Summicron 50mm  (7
element) which was very hazy.  Allthough I wiped the element behind the
aperture *very* carefully with a microfiber coth soaked with isopropanol, the
coating came partially off. In order to have it recoated, I had to remove the old
coating completely. I was sucessful in using toothpaste for this purpose.
