Most of you are probably already aware of the two printing varieties in the 2006 $20 notes, either from this forum or from Coin World's article a while back. I've put together
this page on my website that explains the varieties and summarizes what's currently known about the serial ranges for each. You'll notice, though, that there are still a lot of ranges listed in gray, which means no notes have yet been reported.
That's where y'all come in.

It'd be a big help if you could check your 2006 $20's against that list, and let me know if you find any from the unreported ranges. Also, of course, let me know if you find any notes that contradict the listings I've already got--as that page points out, some of the listings are based on pretty thin data, so it's entirely possible that an error or two has gotten by.
Thanks much for any information you can provide!
