In general, if you're going to think about going after unlisted varieties it is best to stick to high grade coins. Just too hard to convince anyone exactly what is going on when there are a lot of dings and environmental issues. It's hard enough to attribute known varieties on good coins.
For example, here is a 2006 WDDO-006 I just pulled out of a bank roll. The obverse is maybe AU with the usual light staining and browning and all that. But even with a known variety, on a half decent coin, look at the arrows in the photos and see just how minor the splits are on the serifs. Yes the base of the Y and right arm are thicker (that's what I saw that made me look closer), but to really figure the coin out you have to be able to see the details. Even a few very minor dings on the coin and the doubling quickly would become very hard to differentiate.
You are looking in the right place and for the right things, but better to shoot for things on better coins if you want to figure them out.
Good luck!
