I don’t buy the Berger’s 52 Topps river dumping story. More like CCC (had Topps connections) bought the leftover 52 inventory (including uncut sheets), had them cut, & sold what they were able to over the next 10-15 years. Then their 1975 fire warehouse fire wiped out some real treasures including their hoard of 71 Greatest Moments test cards.
According to lore, rumors, etc… going back to the 1980s (when I collected as a kid), word had it Rosen & others came across uncut & large bordered 52 Topps 5th & 6th series sheets
in addition to the 1986 52 find. Had them cut from sheets / trimmed & sold them. In my opinion, this is likely were many of today’s high grade 52 Topps 5th & 6th series originated from.
Please note everything typed in this post is my opinion & pure speculation .
