Keith O'LearyI've sent in a couple hundred T3s and T9s for grading. I usually put them in individual 6 X 8 top loaders, sandwich them all between 2 cardboard slabs with the submission form, put a piece of tape across all 4 sides so nothing can slide out, wrap that in a couple pieces of newspaper, box them tightly (with more newspaper) in those 4 X 11 X 14" priority boxes, use brown reinforced tape across all visible seams, then register / insure USPS them.
