Awesome coin! It does appear to be an N-3 Medium letters variety.
A great quality of the large cent market is that a huge portion of EAC collectors still purchase and hold onto raw coins. For that reason, and the fact that this would likely be a details coin, I would lean toward not submitting the coin. If the surfaces were perfectly smooth and the coin amazingly choice, I would lean toward
TPG submission.
In the end, it depends what you want to do with the coin. If you would like to auction the coin, it would need to go to a
TPG. If keeping it, might as well maintain it as-is!
