I would guess the albums are from 1957 since that's the last date in the album. There are several blank holes after the 1957 date for expansion into the future ...
Some more info on the albums from
http://www.coinbooks.com:
Dave Lange writes: "Martin Luther Beistle was awarded U.S. patent
number 1,719,962 for the Unique brand coin album. This patent was
later sold to Wayte Raymond, who marketed these albums through Scott
Stamp and Coin Company as the National brand. That brand was marketed
into the early 1970s. I believe that this was existing stock from the
1960s, as I've never seen a mintage figure for dates later than 1964
or so.
And for those of you fretting about acidity and toning, I don't plan on putting together a collection of any particular value. I used to have more fun collecting coins out of circulation than just buying what I needed. Finding the 1959 spurred the idea of revisiting collecting the old way (or at least as close as I can).
