There are no mintmarks on Philadelphia struck Ike Dollars. Dollar coins had a P punched into the die for the Susan B. Anthony dollar. I edited to add there is a Variety 2 listed in the RedBook, but, there is no mintage for it and there have been zero certified. Your coin is not a proof either. Also, when looking at the reverse of the nickel it looks like there is a coin rolling machine mark on the coin. Maybe it is the plastic. All of those are circulation coins.
The coin sets that you have were made by third party companies and are not official US Mint proof sets. The sets that you have were made by taking circulated coins, polishing them to death, and placing them in a cheap plastic holder. All of those coins are circulated business strikes and are in no way related to proof sets. I suggest you do some research and learn the difference between proof and business strike coins. Good luck Also, you should make new threads for each new coin/question that you have.
Thank You and sorry I’ve not got all the thread stuff down yet. Looking for it now going to post some pictures for a friend and ask for some advice now I can’t find new thread button
