In 1997 and 1998 Pinnacle produced cards which they sold in a collectible steel can. You actually had to use a can opener to get the cards out.
There were ten cards in the can (they were packaged in clear cellophane) and the can cost $2.99.
There were 24 different players featured on the cans. Checking on eBay I see, you can buy any number of the cans for a buck. I've got 8 of these (one from '97, the rest from '98). Although they are 10 years old, they've held up well, by which I mean they are not rusting.
On the back of the can are Product Facts giving "% Daily Value"
Collectability 100%, Top Players 100%, Inside Info 100%, Cool Inserts 100%
The rest of the product facts give the odds on inserts: Stand Up Guys (1:1). This was a two piece thing with slits cut up the center of the pieces. If you slide the two pieces together it would stand up! On each interior face a different player could be seen across the two pieces. I hated these.
Club Edition (1:7). This was a gold Dufex finish version of the base set.
Behind the Numbers (1:23). I don't have any of these.
Inside Gold Can (1:47). I don't have any of these either. It says this is a can. Was the inside of the can gold plated?
Diamond Edition (1:67). None of these either.
On the side it says "The Only Baseball Card in a Can"!
The cards were ok. They were glossy with silver foil on the logo and player name. There weren't many subsets, just a rookie subset and checklists cards with a player featured on the front.
Ultimately, I didn't really like the cards which is why I don't have many of them. I think I've seen the cellophane packages recently in repacks.
And as a collectable, the cans are a pain in the neck. They are about 4 1/2 inches tall and a little wider than a card. I've got mine in a box in the closet.
I already had the Ripken can scanned (that was an adventure). I pulled out the Scott Rolen can to look at details. I'll probably leave it on my display shelf with other Phillies stuff.
