A new concept in parallel editions was debuted by Ultra in Series 1. While sharing the card numbers with regular issue Ultra cards, the Gold Medallion Edition features a "G" prefix to the card number and gold-foil highlights on front. Unlike past parallels, however, the '97 Ultra Gold Medallion and Platinum Medallion inserts share a photograph which is entirely different from the regular Ultra base cards. Gold Medallion Edition cards are identified as such in the lower-right corner and were inserted at a rate of one per pack. - 2007 Standard Catalog of Baseball Cards, 16th Edition.
