3 1964 Kennedy Half Dollars

This auction is for the 3 1964 Kennedy half dollars pictured here. I am not a coin dealer - just your average Jo - so I do not know how to describe these properly. But I will be more than happy to answer any questions you may have. 2 of these coins do not have a mint mark on them one has a "D".
They have been circulated. The total weight is 37.5
I will send them along in a padded envelope first class mail.
Thanks for taking the time to look.
