John F. Kennedy Half Dollar Collection Starting 1964 — Blue Book — With 19 Half Dollars Included

This blue book is in good condition; and contains 19 coins:

1964, 1964D, 1965, 1966, 1967, 1968D, 1969D, 1971D, 1972 — those are in their appropriate slots.

Then there are 10 extras to the right. Looks like there’s a 1974 and a 1978D, and the other 8 are 1964s.

You know which ones have silver content.
