   If you are interested in U.S. coins, you should obtain a current (2024, 2025 edition likely to appear in a few months) or recent edition of A Guide Book of United States Coins, commonly known as the "Redbook". It is available online from its publisher at whitman.com. There you would find that the 1974 Lincoln cent (no mint mark, Philadelphia mint) had a mintage of over 4.2 billion pieces and the 1968-D (Denver mint) Roosevelt dime a mintage of nearly 481 million. They still circulate in the United States and have no value to collectors unless in uncirculated (new) condition and even then only if attractive with minimal blemishes. Both of your coins are worn and have no collector value.  (I assume that the "wheat ears" reverse is from a different cent, as that reverse was not used after 1958.)

   The non-U.S. coins also appear to be common modern issues with circulation wear. You can check their retail values on the NGC World Coin Price Guide at World Coin Price Guide and Values | NGC (ngccoin.com).

@hixxstersmine--   Please post your questions about coins on one of the forums, such as the "Newbie Coin Collecting Questions" forum, not in someone else's journal.

  Your photos of the 1943 cent are too dark for me to offer any meaningful opinion, but many thousands of dark or rusted 1943 zinc-coated steel cents have been privately processed, replated and buffed to appear uncirculated.  They are identified by a shiny rather than frosty surface and are considered to have an altered surface.  It's possible that NGC was wrong, but they have to go by what they can see. There's no way for them to verify that your father got it "fresh from the mint" in 1943 and no one has done anything to it since.

FYI, here's what an uncirculated 1943 steel cent is supposed to look like, this one graded MS 66 by PCGS.
