Greetings From Pennsylvania - Lincoln Cent Errors?

It's a pleasure to meet everyone.

I suppose I should start my first post, with a few things about myself. I've been collecting coins off and on, for over 30 years. When I was little, my parents bought me the Offical Whitman Coin Folders for Lincoln Cents.

Over the years, my uncle has given me coins and paper currency from all around the world. A few years ago, I was coin roll hunting for silver and wheat back cents.

I recently got back into coin collecting earlier this week.

While I was searching for a list of the different errors on Lincoln cents, I came across this forum, so here I am.

I found a few strange Lincoln cents the other day, so I am posting pictures of them, to see if anyone might know what happened. I'm thinking that these may be diecapped or extremely broadstruck? I haven't learned all of the different terms yet.

Sorry in advance if the pictures aren't that clear, they were taken with a cellphone.

These are three different coins. Front/back, front/back, then back/front.
