I was recently repaid a debt in mostly brand new $20's. I noticed that several were from two series, and in serial. Not only that, but the serial numbers matched exactly except for one digit. An 8 in one series, a 4 in the other. I know some paper money is valuable due to unusual numbers, such as radar notes. So, any value to these $20's? I have 3 or 4 matching pairs.
I think you a talking about having what is called sequential serial numbered notes. Which will not add any value above face value to your New Notes as these are quite easily to get from any banking institute. The unusual serial number thing is all together different. The are Fancy Numbers. Look Here. https://www.pmgnotes.com/news/article/5901/Fancy-Serial-Numbers-On-Currency/

They are not consecutive. Well, one was 40,000 behind the other. The numbers are...…. ME 70484538 I ME 70488538 I if 40,000 apart is considered consecutive. Cant imagine the odds of this happening in a handful of bills. I should have bought a Lotto ticket while I was lucky. Given that paper collectors will collect even common modern bills if it has an interesting serial number, ala radar notes, or errors, I thought I would ask here.
