thanks for all the great comments guys.
Metallica - i am collecting the best looking patches i can get my hands on of the player, not worried if # 75 or 20.
Nandalinnaung - The cards that are # 20 have the writing in gold and the cards # 75 have the writing in silver. It is a bit confussing with the Oscar Roberston card because both the Gold & Silver additions are both #20.
Jza - the Oscar patch card i got through Maurice in the US, he new someone that was selling it, i bought it as soon as i could because as you know they don't come up to often on ebay. Cost me $115(way above the book price) but who knows when the next on was going to pop up so i wasn't going to miss out on this one.
