I just back separte auto;s of each and the guy who verified my auto;s said Maris was going at 750.00 and Mantle whatever the market would give u.
Mine was on baseball cards of each so some will say one figure and others will disagree which every person has there own opinion which is understanable.
But i am telling u what the gentlemen who verified and slabbed mine stated to me.
