I recently acquired these 2 notes with the same series and serial numbers (acquired about 2 months apart). I've searched the internet for their value with no luck. Hopefully those with more knowledge in this area than myself can help.
-The upper note was issued directly from our local bank with several other sequential notes. I would grade it a CU note.
-The lower note was purchased through an online auction. I would grade it a AU note.
I won't say anything about "binary" but to me this is a case of the product is more than the sum of its parts. How much more...well... dunno. The serials are pretty cool, no doubt, and together I think they are a very attractive pair. Maybe list the pair for $100 or $120 and see if you get any bites. That's a wild-ass guess for sure.
