Cards that do not exist

There are several cards on the list that I do not believe exist and therefore, need to be taken off the list:

• 1996 Topps Members Only 55 #18 - I believe this to actually be a dupe listing with the correct version rightly listed under 1997.
• 1996 Pinnacle Aficianado First Pitch Preview - although cards were made of some players, Juan was not one of them.
• 1997 Leaf Fractal Matrix Die Cuts - both X axis cards, Y-axis #101, and Z-axis #353 - I have only ever seen or heard of the two we have pictures of on the list.
• 1998 Pacific Online Winners - all three cards - Never seen 'em.

Now I know that just because I have never seen a card doesn't make it not exist, but these are cards that I don't think any Juan collector has seen. Please prove me wrong. Maybe some of our newer members can help with this??
