So as the US moves forward with removing pennies from circulation my work finally stopped getting them with the attempts of removing them from the store. I've gathered tips and traded some quarters for some pennies as I'm trying to do Penny presses to honor a loved one. 

Checking the years to get certain ones, this one has an "apostrophe" after the year. It is not dirt, it is raised like the year is raised, and besides that it looks like the whole front design looks like it is slightly adjusted upwards as well. I did include the back side of the penny just in case. If anything I did notice that there was an additional partial ring where it says "in God we trust", but again nothing else besides the apostrophe seems out of the ordinary for me.

Any educational information would be absolutely wonderful. I'm not asking for value, I'm not asking about anything but how this could be on here, and why. I did and still am doing my research, a general Google search couldn't find anything with an apostrophe. My friend thinks it could possibly be something to do with the dye. I would ask the only expert that I knew but as I mentioned in the first paragraph I'm collecting to honor a loved one. I could pull out a Ouija board, but this seemed a lot simpler lol
