Welcome to the forum.
I am curious to know what you think (or have been led to believe) that these coins might be worth, and why. These are quite common, and, as Coinbuf said, not even worth the cost of shipping unless in very high grades.
There is a lot more to a coin's value than age and "shininess." And, if you are getting your information off youtube, I suggest you stop trying to buy or sell until you have gotten all of that nonsense out of your head, and picked up some truth, either from books like the Redbook, (A Guide Book of United States Coins, by R.S Yeoman) or other sources of legitimate coin info. In addition, we are happy to help you learn, if you are willing.
Edit: I forgot about the 1970s small date. If you have one of those in really good shape, you might could get 10 bucks for it.
