Is this what Topps meant by "Added Value in Every Pack?"
Courtesy of the must-read Sports Collectors Daily:
"Topps is confirming that because of what it calls 'a manufacturing error' in the recently-released 2008 Topps Moments & Milestones Baseball, card numbers 145-189 feature more than one red parallel.
"By design, each of the Rookie Cards 145-189 should only have one Red Parallel (1 of 1), but because of the error the subjects have an additional 20 Red Parallels."
In other words, the only "true" ones-of-one in TM&M -- and the only ones-of-one that might actually be worth more than the price of a waxpack -- are actually 20s-of-one.
