Looking to find out which of the Topps Traded and Fleer Update sets of the 1980's were actually factory sealed. I can not find the actual documentation online anywhere else.
Strictly speaking for the 80s, and not the 90s. Topps only used a single piece of clear tape. Donruss didn't seal their Rookies or Highlights sets in any way. Fleer used a cellophane wrapper on their update sets starting in 1987, but the 1984-1986 sets were not sealed in any way. Score didn't seal their sets in any way until 1990 when they used shrink wrap.
