General Forum

Apologies if this has been addressed. I searched some of the forums, but didn't see anything and I'm fairly new to loading cards onto here. I am assuming that NNOs do not count toward the number of original card total, correct?

For example, I'm entering my 2018 Topps. The site says I have 285 cards in the set. I also have 193 duplicates, so 478 total. Stats page says I have 479. Having double and triple-checked my checklist, the one outlier is the NNO. 

Thanks.
