Is there a lot of Red on the RB side, is there any Red on the Brown side?
I actually see very few coins that have a big difference in color from one side to the other. Where there's a small difference, the overall appearance of the coin must be considered. This is really one of the most subjective calls in coin grading.
Thanks,
