Ryan, when you're ready to take your set to 525, I have the first authentic Nodgrass that PSA ever graded...I kid, I kid (but I do own the Nodgrass)
I mean, ever since I started collecting T206, 30 years ago, the known complete set number was always (will always be) 524 (it's well known, that we don't include printing variations in that number). The big 4: Wags, Doyle, Plank, Magie. Hopefully if they see your thread, they'll make the proper updates to the lot title and description.
Lot Title should read-
"Near Complete T206 Set, Missing Wagner & Doyle. 522/524 cards, plus Nodgrass variation"
