1990 Topps Traded Baseball was released for a short time in wax packs/boxes, only at retail locations. One of the main differences between this version and the boxed versions, is the card stock that Topps used. Like many other Topps Traded sets, the boxes version cards were printed on the bright, white card stock. 1990 Topps Traded wax issued cards were printed on the regular, old, card board stock that Topps had been printing it’s base cards on for ages.
But we’re not done yet. Another variation exist that affects only the wax-issued cards…
Each card found in wax packs of 1990 Topps Traded can be found in two different varieties: One, with a single asterisk * before the copyright line on back. And two, with double asterisks * * before the copyright line on back.
For those keeping score at home, that brings the grand total of 1990 Topps Traded cards included in a master set, to 396! And if you count the Tiffany edition, 528 total cards!! That’s a lot of variations for an update set!
Oh, and dont forget to wash, rinse and repeat for the 1991 Topps Traded set.
