1993-94 Upper Deck Special Edition Basketball Forum

I found these two variations of the Upper Deck hologram logos. The cards are numbered G4(Charles Barkley, gold hologram) and G5(Hakeem Olajuwon, silver hologram). There are at least 2 differences in the holograms. First, one is colored copper and the other is silver. Second, one hologram has the letters spelling UPPER DECK in gold and the other silver. Here are pics! Please tell me what you think!
