Good finds, the 1964 dime looks in great shape. I make a point of allways looking in our local supermarkets "coin star". I had £7.60($9.50US)the other day. How do you not notice that amount of change not registering??
There was also a 1977 1/4 dollar. I don't think its worth more than face value, but it all goes in the foreign currency collection box.
That sounds like a huge score. 1977 Washington quarters are face unless uncirculated
