Do note that there are two versions of the Dansco. One that includes the proof only issues, one that does not.
Proof only means that the coin was only issued in proof for that mint, typically the 1968 and later San Francisco coins.
Sadly, for the years that Philadelphia (1964 and earlier) and San Francisco (1968 to 1975 cents, 1968 to 1970 nickels) issued both proof and business strikes there is only one hole so you have to choose which to put in it.
