What mantle factory issued autos are there?
 

91 Score subset, 92 Score Franchise, 94 Mantle/Griffey, what else?

There was a set issued in 1982 Mantle ASA I think, 50-60 cards detailing his career that contained some sharp autoed cards.

That's pretty much it unless you want cut autos.

If you want real oddball R&N China created a set of Mantle Topps replicas which were signed. There were also some signed porcelain cards by Sports Impressions in the 80's that were issued in conjunction with their porcelain statues.

I think that Upper deck had another card but not sure if it was pack issued or a UDA issue.

1994 Upper Deck All Time Heroes, pack issued, I believe 1000 were signed

I saw one on ebay slabbed by PSA, but it was designated "Trading Card" with only an Auto grade which I thought meant it was an after-signed item. Maybe there are some of each?

I looked at the ine on ebay listed for $1800.00 it has the upper deck code and correct holo for a pack issued card. If it was signed after at a show It would not have the UDA code and correct holo.

We may be talking about different cards, I was looking at this one but it has no back scan.

There was a pack inserted Mantle in that set. There is a Seaver from that set too. Might be one more that is slipping my mind too.
Reggie Jackson possibly?
