There's also a square-cut set, which is supposedly rarer than the rounded one, and supposedly carries a premium on the price......but I've seen a LOT of them so who knows?

There were literally millions of these glossy sets made with rounded corners, most can be picked up for less than $10.00 per set on eBay.

The squared cornered ones are the collectible ones, but no idea how many are out there.

The square set ones are more collectible just because there are less of them, but by today's standards, the print run is still high. I never found out what the exact run was for the squared off corners, but I've never not been able to find a set available for around $20-$25. So....

Actually hey are quite common, I bought 2 sets for 1$ + shipping around 4 yrs ago.

There are also Topps versions of both the round and square sets, so there are a total of 4 versions of each card.
