Amazing find, I agree with you, the left hand card looks like 1998, there are other subtle differences, the 1999 looks to have aholographic foil, (my Vinny Testaverde has the same foil look), the 1998 appears to have a registered trademark, my Testaverde and your 1999 Enis do not have it.

Amazing find, I wonder if there are other '1998' versions

Thanks man. Yes, the one on the left is definitely from 1998. It is hard to see but the copyright near the bottom reads 1998 as well. From looking over my other Enis auto cards it seems that he stopped from signing his auto with a jersey number immediately after his rookie season. It is also odd that Enis was not featured on any other Donruss cards that year.

I too wonder if other "1998" Donruss Private Signings of other players are floating out there.
