original AR lens - 2 types?

I just replaced the original blue AR lenses on both my players in the last few days. Now, I have both blue lenses here. I happened to flip both over at the same time, and noticed the AR coating on each is very different looking. One looks shiny-greenish-blue, while the other looks shiny-deep-violet.

I'm going to have to experiment with some sunlight and see if there's a difference between the 2.

The AR coating isn't shiney in any colour. You're looking at the ITO coating on the rear face which is there for EMC compliance reasons. The AR coat is on the other side.

Ok. I feel stupid now.

I wouldn't. Not everyone knows ITO when they see it
