All of the 1c, 5c and 10c "No S" coins are proof coins. Unfortunately, we get this same question dozens of times a year, and so far, all of the coins posted here, like yours, have been business strikes, not proof coins. If you plan to search for varieties and errors to make your fortune, my suggestion to you would be to learn about the minting process, first, and maybe in 50 years or so, you might get lucky and find a coin that will make your house payment for a month or two.

2 of your coins have a mint Mark. The 2 middle coins are Denver mint. You have to search proof sets to find no S coins.
