No, under most conditions. Coating on the front
surface is unnecessary, but it is more useful on
the rear surface (that faces the lens front).
I prefer single-coated filters for the greater
ease of cleaning them - a clean filter is
better than a multicoated filter with smudges
on it...;-)

More of an issue is whether or not the filter
is likely to be flat, and has a good enough rim
to hold the glass properly without intruding into
the image with wide-angle lenses... BTW, for
relatively inexpensive, but good, filters, I
prefer Hoya single-coated metal-rimmed versions.
