Those are some nice BU cents you have there!  If you like them, and want to submit them to NGC or PCGS of grading, go for it!  However I would like to advise you against that particular way of preservation.  These coins have a value much lower that the submission fee.  I have been "specializing" in collecting cents for the past few years, and I recommend storing them in 2x2 cardboard flips for now.  Who knows if you pass them down tor your prosperity what value they might hold in the future!   Cheers!

That is exactly what I have ready for them,2x2 flips. I've taken them out for photos purpose only and have new flips. I'm so worried about oxidation. I've been using silicone dioxide packets in the box I store my 2x2s into.they look good so far hope they hold the luster. Thank you for the observation and input is greatly appreciated.

Don't worry about the oxidation.  As long as they are stapled in 2x2's, there is no need for silicone.  But I applaud your initiative to stay on the conscious side.  This will serve you well if you decide to continue in this amazing hobby.  When I first started collecting as a 9 year old 7 years ago, I beat the out of my coins, and did almost all the wrong things. I am glad to see that you are not making any of those mistakes.  Also, if you have any numismatic questions but don't want to put up a forum, feel free to message me directly and I would love to help you out.
