Is this 20c "S" or "CC"?

I had this marked as an "S" but on second review, the top loop doesn't look like an S loop and also I think I see a "C" where the second "C" should be. What do you think? And what should I do with it? Should I have it authenticated/slabbed since the mintmark is so hard to make out and the differences in S and CC are quite dramatic? Does this look like it would grade PO-1?

Trying to make it even uglier?
Looks like a C...C to me. Nowhere to punch them close together on that die.
