Just curious if any of these are worth holding on to I no nothing about coins and the nickel is it just washed in washer to many times or is this an error
1972-D Eisenhower dollars really don't carry a premium in Circulated condition although they are the last of the big dollars and are still cool. For it to have any significant value above face it would have to be graded MS65 and above or have some cool toning pattern. The 1972-P Eisenhower dollar has a rare variety known as the type 2 reverse but from your pics I can see the Denver Mint mark below Ikes head.
The nickel is damaged. I'd value that collection in the $5-6 range if sold privately (i.e. a coin shop would not be interested).
The nickel is very damaged. You might get $5.00 in a private sale but I doubt a coin shop would be interested.
