71-s Lincoln Proof Dbl Die question

Can one of you experienced Lincoln folk tell me the difference in the Ty I & Ty II Lincoln proof 71-s dbl die. Someone locally uncovered a 71-s Proof set with a 71-s dbl die. It looks identical to the redbook example. He is intrested in selling it as well I believe, and I would like to get first shot at it especially if its nice. I saw it quickly a few weeks ago, and want to look at the condition again, but I believe its quite nice. Also, do anyone have idea about what it would sell for : He is hung up on the redbook price listing???
Thanks
