No, they were originally single-coated. It is high-quality, and can look multi-coated. A few lenses could have been returned to the factory and later multi-coated. But with so few air/glass surfaces, the difference would have been minimal.

Multicoating???
Multicoating???
Does multi-coated means all elements are coated or they have a several different coatings on front and rear or all of the above.
Brian did you receive the case.

I second Brian on that. J-12s were not multicoated. The front element is well recessed and the rim of the lens acts a natural hood. The internal surfaces are coated, and so is its bulging rear.
Multicoating was probably never applied on Soviet LTM. The 'MC' appeared only on their SLR lenses.
The coatings tend to vary in colour. The early blue coated ones tend to produce greenish yellow images. The later purple ones from more recent times tend to produce neutral or close to neutral images.

Yes! The case is beautiful! Thought I posted a reply, but must have forgotten!
Multicoated means each glass surface has several layers of coating on it, to optimize for several wavelengths. Often on a single coated lens, the single-coated layers of the different air/glass surfaces are optimized for different wavelengths. So each surface will reflect a different color. I had one J-3 that looked like it was coated for Infrared. The peak reflectance was green.
