I think my source is drying up as I just bought his last one listed. There are quite a few offering BOTH nickels but I have only targeted the buffalo and I think most dealers are trying to use the buffalo to get rid of the "Ocean in View" nickel as well so they are offering the "2-Pack" which is fine if you want to pay the same money for both nickels or if you desire both. In the end I think they will ALL rise in value but as we all know, "AMERICANS are crazy about their BUFFALO" and that will probably be the key! Just my gut feeling at this time. I would say if you want the buffalo BUY THEM NOW as they won't get any cheaper, regardless of who is busting the proof sets, dealer or collector, as sooner or later THEY won't be busting them open as the market dries up for singles. Buy them now and in about a year you will be glad you did. Time will tell!
