Condition ranges from really bad to nearly uncirculated. A spot check of the coins while taking the pictures showed some dates in the 1930s, 1940s, and 1950s.
Definitely plenty of 1964s and the condition of the older coins tends to be much worse. I did not look up any of the dates and most certainly did not pull any of the coins. If you are collecting, then I hope you find a few to add to your collection. Otherwise, these are bulk 90% silver coins.
