while I'm a teen tiny fish in the '14 collector world, I've never crossed any over nor sent any in for grading. But I have cracked a few out (kept the flips - didn't report to PSA/SGC) which are in binders now, including Knabe, Oldring, Grover Cleveland, Speaker, Bresnahan, Strunk, Thomas, Crawford, Comiskey, Bush, Doyle, Rusell, Evans, Rariden, Laporte, and Reulbach. I have around 70 of the 144 cards (most of the less expensive commons) almost all in lower condition. About 1/2 my set is graded (purchased that way) mostly 3's which I'd be happy to downgrade to pick up some tougher cards, but I enjoy cracking them out on rainy days to put in binders.
I'm hoping the set goes down a little in price so I can buy some more - I've been dabbling the past few years but never gone in head first and certainly not doing that now haha
edited to add - thanks Greg for your hard work in putting together the pop reports!
