After showing us an amazing collection that will be appraised by Just Collect that includes more than a couple of dozen Mantles, many from 1965, along with some Hank Aarons and Roberto Clementes, Leighton Sheldon of Vintage Breaks and Just Collects tells us that scouting the grading companies is important. Understanding how each company approaches the problem areas of your submissions could net you an extra .5 or even an extra 1 in your grade. Then he shows us how grouping your submissions correctly can help garner you a little boost as well. Find out how in the Loft!
