I think if there were a T206 Wagner for sale from the state I live in (Arkansas), I would have heard something about it
The only other one I have heard of was owned by John Rogers who bought a real graded one for 1.62 million dollars and flipped it and is now facing criminal charges for fraud (although not connected to the Wagner card). SomeONE would have leaked news about a Honus...
I've never heard of SCE grading service but apparently if you want to sell a high-dollar card on eBay which is likely a reprint, you can skirt the necessity of selling it as a reprint by getting it slabbed by some fly by night service.
Again, if you have a T206 in this condition and have it graded by PSA or SGC you can sell it for a king's ransom. Why would you leave $400,000 on the table by not doing this one simple thing? My God, send it to PSA, SGC, BVG or GAI and get your money's worth, even if it came back Poor or Authentic. It makes no sense unless it is a reprint...
