If you have one, you should be able to see the color shift in reflections from the lens surfaces. Uncoated lenses generally give a pretty color-true reflection; coatings alter this (old coatings, from before about 1970, are usually bluish, newer ones might give a green or gold or even occasionally red tint to the reflection -- though I've only seen the latter on binoculars and rifle scopes).
Can't be sure, it was a long time ago, but the first MF camera I had was a Lubital, and I believe the lens was coated, for the price it wasn't bad, took some nice photo's, and somewhere I have a few of the negative's from it
That's not all coating, I don't think. To my knowledge that's a specific type and quality of coating. I know all Industar 26m for LTM was coated, but there are ones with red P and ones without, and the red P ones are said to have better coating.
