1998 Topps Tek Baseball Forum

Was each pattern of this 8100 master set put out in the promos by Topps? I'm asking because I own the Clemens card marked pre-production on the back over the card number and it's different from what's shown. The number on the pre-production matches the pattern used in the set. According to Baseballcardpedia only three players were used in the promo set: Clemens, McGwire, and Mondesi. I'm just unclear if they used all 90 patterns.

Secondly, I'm unsure if this Clemens should be posted as a promo like the #60 card has been.

I was just looking at these on Comc and Beckett - although there is no way to confirm for sure, it looks like there may have been pre-production versions for all 90 patterns but with only 3 different players - Raul Mondesi (1, 4, 7, 10, ...), Mark McGwire (2, 5, 8, 11, ...), and Roger Clemens (3, 6, 9, 12, ...) - this is based on the numbering I saw there.

Comc/Beckett/Ebay have: Mondesi 1, 13, 22, 40, 55, 70, 76 - McGwire 17, 47, 50, 68 - Clemens 24, 30, 42, 45, 51, 54, 57, 78 - which all fit the pattern.

It looks like they may have been issued in packs of 3 - 1 pattern for each of the 3 players.

Is this enough evidence to create a pre-production set of 90 based on the pattern noted above?

Yes, a couple McGwire master collectors (Onionring in old forums/boards is one) confirmed years ago that all 90 pattern exist for the pre-production cards.
