There's a ton of info on this is the archives. In general if a Zuiko has
green reflections it is MC. Sometimes the green reflections are hard to see,
though. For example, my MC 50/1.4 hardly shows any green reflections at all.
On my 100/2 they are easy to see.
Another way is to check the markings on the lens. Obviously if a lens is
marked MC it is MC. The older Zuikos, with labels like F. Zuiko (where F=6
elements, G=7 elements, etc...) are usually SC, although I think some were
always MC, like the 18/3.5.
There is a MC/SC coating list on Lee Hawkin's site
http://www.astro.wellesley.edu/lhawkins/photo/photo.shtml
it includes S/N's, so you may be able to figure out from there, too.
