Show Cards?

[Sheesh]

I've been busting into boxes filled with top loaded unsorted singles. Lot's of RCs in there (Culpepper, Moss, McNabb, Holt, Green)! After an unsuccessful internet search, I have questions regarding a few.

I have found a bunch that I believe (but am seeking confirmation) are trade show cards. For example, a Corey Dillon 1998 Playoff Prestige #129 that is marked on the front "Playoff, 19th National, Chicago 1998". Another example is Ben Coats, Pro Line 1996, #115, "1996 Anaheim, The 17th National, 1 of 499". I've got a bunch of these. Show cards? Value greater than those without as stamped?

Additionally, I have a bunch that seem to be related to the Super Bowl and shows associated with them. For example, Terrell Davis, Playoff SSD Momentum, #73 is stamped on the front, "Super Bowl XXXIII, Miami 99". Another is a 1991 Pro Set that has Super Bowl XXV and Superbowl Card Show 11, January 24-27, 1991. This card has a $40 price tag on it from the fella that originally owned all these cards, which makes me think it is valuable? Is it?

Anyway, I think these are show cards but am seeking confirmation.

Thanks!

Here's your answer - Some Past Show Cards on eBay

As you can see, the going rate for "Show" cards have dramatically decreased over the years - there used to be a decent market for the stuff (mainly player collectors), but not much interest anymore. However, if you have any Brunell's I may be interested.
