Net54baseball.com Forums - 1996 Leaf Collector's Edition Autographs

I recently picked up one of these sets as part of a collection and it came with a Leaf Gold Rookies Marvin Harrison card that I assumed was signed TTM or at a show or something. It was a cool bonus but nothing to write home about. Turns out these were inserted into the factory issued sets at one-per. There's ten different players. But after looking online, it seems like most (all?) of the other Harrisons I've seen are either 1. missing the autograph altogether or 2. were missing the autograph until little Jimmy figured he'd do it himself.

My questions, if anyone knows:

1. Are these rare (authentically autographed)?

2. Any idea how much of the assumed print run escaped without a signature?

Thanks

Arthur
