The stated odds per this Beckett Plus magazine I am reading for the 1997 Donruss Signature authentic autographed insert card set is one overall autograph per pack. These cards are not easy to get and are valued accordingly because many are short printed and there are many that are commons. The Nomar Garciaparra, according to this Beckett, is worth $200 and that can be attributed to there only being 62 printed of them. Commons in the regular autographed set are worth $5 per this Beckett. There is the regular autographed set, the Signature Autographs Century (which there are only 100 of each card or less printed), the Signature Autographs Millenium (1000 of each card printed), Signature Notable Nicknames, Significant Signatures (2000 of each card printed), and various other cards as sometimes there are more in packs than are promised in the book. The best cards in the set are worth up to $800 (A-Rod) per this price guide and they are from a myriad of great players including the rookie year autograph of David Ortiz which is worth a whopping $600 (for the one that only 100 cards were printed of). The regular autographed set card of David Ortiz is much more affordable at $50, and this is because there were 3900 of them printed. Even in the regular autographed set, the Tom Glavine is worth $80 and the Wade Boggs is worth $150. There are so many great cards in these sets that there are too many to mention in this article. Please enjoy shopping for these cards at sale prices in the listings here on this page.
