There are 3. 1) die chip, common, not valuable 2) The D was damaged, not valuable 3) Not sure what you were trying to draw but probably just split plating. It's a copper plated zinc.
Welcome to the forum! As you can see, even the most expert of coin collectors like @BadThad are glad to answer your questions. You are in your first phases of coin collecting (been there)...the coin roll and error searching. Hopefully you'll enjoy the hobby, read a few books about whichever coin you're interested in and run with it. When I first started, I was all over the place, mint sets, modern coins, random auction purchases, coin roll hunting and now am on to Lincoln Wheat cents and studying Large/Half cents (but not buying yet...book before the coin!). Key is to enjoy the hunt, know the lottery is still the lottery with very low odds and appreciate the beauty and story behind the coins you are interested in. Also...best advice I can ever give you...age and mintage don't necessarily equal rarity and value!
# 1 is allways a good reference. Shut! Number 2 is pretty convincing itself looks like @stldanceartist avatar.
Sure keep the 57 D as an educational item for what a die chip looks like. What's it going to cost you one, two cents? The 77D is normal, and the cent reverse you showed looks like damage from a scrape the tore away the copper plating exposing the zinc underneath. The rest of the coins appear to be just pocket change with the exception of the 1988 S proof nickel. It might have a retail value of 50 cents or so.
