I've had one of my cards identified as 1996-97 Pinnacle Zenith Champion Salute Extra

Looks like these:

But I can't tell if it is just a 1996-97 Pinnacle Zenith Champion Salute

This is my card:

What is the difference? They look identical to me. What am I missing? What is the Extra part?

If it is an extra card, what kind of premium does it have? Est. value. No on COMC or eBay to get a price for.

the Salute Extra cards used a manufactured Diamond much like the Panini Flawless cards did a couple of years ago.there would be an actual diamond chip where the metallic foil is on the lower left.the standard version is just a crinkled bit of foil.
