That 1917 is my favorite kind of wheat to collect. Early die state, toned, and showing a nice grainy surface. Beautiful coins.
Wow, I had no idea that DDO traded at such a premium. Images are a bit small, but they certainly indicate you've at worst a bit of an undergraded coin.
I looked at the very big Trueview and I think it's properly graded. http://images.pcgs.com/TrueView/50015093_max.jpg The splotchy brownish haze around the shoulder and head would concern me. An acetone dip wouldn't hurt but I know, you just got it reholdered! I love the '17 DDO. What a cool coin. Lance.
