I was looking on Whitmans web site, and there are 4 different holders that will hold 4 coins ( Bison, map, mountain view, and valley view) Were the holders made for specific years/coins or mints P/D or can you put them however you want them?
I wanted to give a full set of D mint nickels to my nieces and nephews, so I used the map one as the holder even though I think it was designed for the 2004 nickel set highlighting the Peace/Louisiana Purchase nickel. For my purposes it seemed to be the one that covered the theme of all four nickels best.
Of course you can. Whether you want to or not depends on the labeling and display options available with each holder.
