The Red Belt set comprises twelve different cards if you count the Huggins - Second Baseman Par Excellence twice. Only one of the twelve, Opening Day, is considered a mega-toughie and rarely seen. The others vary in difficulty but do show up occasionally. These observations reflect my experience when I collected them about ten years ago. Since then I see them once in a while on eBay and in various auctions. I am unable to say how easy or hard Safe, the one with Collins, is but I expect there are a few around, some residing in collections that will never be complete because of the Opening Day postcard. Sorry my answer is sorta vague. Others here may know better. Good luck.
