Great finds to pay you for your efforts. Several of your war time nickels have that common lamination issue, which I enjoy seeing. The strike throughs are neat, but that beginning cud is really a nice find. Keep up the searches, so I don't have to. LOL
I wasn't into nickels much, but I read an entry about the nickels issued during WWII that the Mint Mark was about the building. Since then I've gotten a few. I bought some through ebay and other sources to buy certified nickels from WWII. I've got several real nice ones.
