I know this is probably a silly question from someone as allegedly experienced as me (and modest of course), but I am moderately new to Danscos, normally being a slabbed coin collector. Does the Ike Dansco album extra spaces fit the two Eisenhower 1990 commemoratives--Ms and Proof ? I'd love to add them to my complete set, and assume they'd fit, but am not sure. (embarrassingly stupid question???).
