It could just be me but how come the photograde photos for Lincoln cent (1909 to date) only uses wheat cents? I thought they should have it at least for LMC (and maybe LSC later on) as well to show the wear and tear. Isn't that the basis for grading?
I think its due to the value of MS-65 RD LWC in the 40's and 50's. That is just my thought as to why. Others will be different i'm sure.
