As to your first coin, I have to ask the question: Why would you want to keep a PMD nickel? As to your second coin, yes, keep it. It is a woodie (improperly mixed alloy) in fairly good condition. It would make a good addition to an album.
Like mountain man said the first is a spender but the second one is a keeper!!! I new if you keep looking and stick around you would find one!! Keep looking!!
