It was nice of chuckbartle to give you the information he did. I know little about coins--just that it feels good to have a few every now and again whether there new or old. Good luck.
These coins you are listing are all silver. This one is Morgan silver dollar, I also see that you have a Peace dollar and a Walking Liberty .50 pc. These should all get 10,000 or more credits. If you have any more from your father, you may want to have them looked at by a dealer first, I don't think the dates you have listed are especially rare, but they do have considerable silver value. There are however, some far more rare dates and versions of these coins. Good luck with your auctions.
according to the pictures there is no mint marks. if there was it would be on the back side underneath the arrows, it is unmarked so it might be a a P.
