1991 Score Mickey Mantle
 

Finally getting around to getting this insert set, and after viewing the available listings on eBay as well as a couple on-line write-ups, I'm a bit confused. There are glossy versions, versions with serial numbers, versions without serial numbers, and then the autographed versions. I'm trying to simply have a set of the version that would have been available in packs.

What is really odd is that 2 sellers are offering complete sets of the serialized version, in which all 7 cards have the same serial number, which makes me think there were multiple ways to come by these.

I'd be grateful for any information which would help put all these differences into perspective. Thanks!

Looks like only the unnumbered and the autos were in packs. The numbered and glossy were released other ways.

Well, I had a senior moment - usually I check Baseball Card Pedia - thanks!
