Way to go. I remember the feeling when my Zimbabwe set hit 100 notes - although some of those where US dollars that I include for my narrative on dollarization - and then it passed up 100 Zimbabwean notes later. 

Side note, but I do agree that most of the a/b/c notes are signatures but you don't get some where it's a change in watermark or a change in another security feature.

Absolutely, there are a lot of small changes that will facilitate a new Pick #. In this set a few are a Latent image was added, a change to the serial number prefix (letters to fractions) and watermarks as you said. All very cool stuff but mainly signatures on any notes after 1992 (issued 1996) for this set.

EDIT: Taking a quick look at this set, specifically Pick 103, the P103a has a notation on the label "Sign. #1"  and P103b has a similar notation "Sign. #3". What happened to Sign. #2 and no slot for a P103c? I'll have to check this out later, something isn't quite adding up.

My guess would be there was a 2nd signer in the middle but that denom wasn't issued / printed during that person's brief tenure.

The RBZ notes have the signatures of the governor and you have some sub-picks that have a signature for a governor that was only in office a few months, making those types relatively rare.

That was my initial thought but the 3rd signer had several signature variations, I think it more likely that Sign #2 is a variation of Sign #3. I'll have to look it up this evening but if I remember right there was not another signer between #1 (Hetman) and #3 (Yushchenko), as I don't think there was another chairman/governor of the NBU in between. Or the SCWPM wasn't sure and left a gap just in case.

I don't see any additional signatures or signature varieties listed for this note in any reference, there are notes of the same series with a third signature (Matvienko) who would have predated both the other signatures. I took a quick look at a lot of other P103's online and I have only found the two signatures, my guess is that the SCWPM either had an incorrect signature listed and then removed it or they purposely left a gap between 1 and 3. I tend to think there was a correction made by the SCWPM and Sign #2 was removed, thus the gap and the Pick # alignment of a/b and Sign #1/Sign #3.
