IMPORTANT GENERIC OBSERVATIONS
- Maybe the tables should display columns numbered right to left, like they are on the plates in reality (or at least on some of the plates — check ECB production videos, showing both whole sheets and control tables):

MYSTERIES
- What is a “charge”? How many sheets are there in a charge, and does it depend on the scheme, or on being a supplemental plate or not? For example, sheets for 5-euro P004 / X notes are numbered in bundles of 100, so that no number is left out (on A6 in consecutive sheets, X000000000000x to X0000000099x, then it jumps to X0000006000x to X0000006099x, and so on, because, on the same sheets, J1 is X0000005900x to X0000005999x, etc.) — in this case, how many bundles make a ”charge”?
- What happens when there are missing cells on a scheme? Are the notes on those cells printed without a serial number and destroyed, or not printed at all? Are those cells missing because of an error at the program responsible for the numeration, is the plate damaged there, or is it for any other reason?
- How and why are supplementary / auxiliary plates used? How can they print such small ranges? Are they used to reprint in bulk entire sheets that came out with errors from the main plates and then destroyed (that is, the so called “replacement banknotes”)?
- I have a sequence of notes with a plate change (most likely for replacement sheets): R007** / RA*******81* (and others up to 81) is followed by R005** / RA*******82* (and then 83 and so on). So, are printed replacement sheets placed in order, in the exact same place of the sheets they replace, before cutting the sheets? This seems to be arduous work and I can’t see the point of it. Check also this case of a single outlier note in (serial number) numerical sequence, printed on a different plate (?!)
- If a specific note in a sheet doesn’t pass control does it go to a pool of error notes until a whole sheet of correctly positioned but unrelated numbers can be printed? Or is that specific serial number lost forever?
- When there are very short ranges of numbers printed on supplementary plates, it’s extremely common that the figures on positions 7 and 8 (or 8 and 9, if you count the letter) — that is, the first figures unrelated with the cell position — are 97-99, or 47-49 (for example, F00950597, H55280198, E07612099, L31152747, F01051048, N**038349, P1794**99) — or any number close to these. How come?
- Some schemes (at least R/R tenners and V/V fivers) are in reality very close to what giulcenc found but not quite, since cell changes are made in the middle of the supposed scheme. Check for example this blog post.
- How can giulcenc know the upper limits of a scheme right after the banknotes had started their circulation? Privileged sources? Relying exclusively on eBay and other online auctions (assuming the auctioneers themselves have privileged sources, so they’re selling the first and last notes of each batch)?
- Does Guy Sohier have physical evidence of every plate he reports as valid? (Apparently not always. ErGo told me that S004 and S005 fivers were for a time on Sohier's liste. I may have found other extant cases. For example, there are no more than half a dozen G006 5-euro items on ET that could be considered likely to exist.)
- Is Guy Sohier aware of all the rare schemes? Some plates seem not to be valued enough on his catalogue. Also, very few of the special schemes are valued differently from their normal combination plate / country notes.
To check in which countries I might find some EBT users with some of the unsolved or partially unsolved numbering schemes, see also http://leopardi.miuku.net/tmp/denomination_serial_detailedshortcode_country.txt
