GHD - M-C signature have strange serial number run

News: Welcome to the Canadian Paper Money Forum.

$50 GHD Prefix with M-C signature is exhibiting some strange serial number-position number condition.

Low number GHD (My guess is that two have been reported in SNDB) i.e. below 200000 (0.2) are exhibiting position  numbers that would start with the Serial Number 0000000 at 41.

However high number GHD (my estimate is that there are no notes reported that are lower than 40000000-4.0) do not follow that PN sequencing and in fact have a different sequencing of serial number vis-à-vis the position numbers.

I am wondering if anyone has worked through the specifics of this situation.

Again the implications are that GHD M-C was printed in two separate runs. It may be a stretch to say this at this time but it may turn out that the numbers of GHD M-C printed may be much lower than otherwise indicated by the present serial number range of close to 5000000 (5.0)

I hadn't noticed how uncommon GHD M-Cs were until you pointed it out. For what it's worth, my records indicate I've only seen 2, and they're both to the high end of the range - 46- and 47-. Compared to 29 W-P of roughly the same size range, that is odd indeed. I will certainly let you know if I find another one (and probably keep it while I'm at it)

I agree: M-C GHD was not a full run. I have not worked out the specifics & cannot help you in terms of speculating what happened to this prefix numbering.

I have searched a large number of $50 notes and only came across 3.  One, unfortunately, I put back into circulation. 

The other two are:
GHD 4742413 39 39
GHD 4756371 06 06

Hope this can shed some light.

So if the two notes you mention were printed as normal PN-Serial Number combinations then:

GHD 4742413 would have a PN of 07 07 and not 39 39 as it actually is and

GHD 4756371 would have a PN of 24 24 and not 06 06 as actually is.

The PN on the notes you have reported are consistent for the GHD M-C in that range.

The PN on the notes that have been reported with serials below 0.1 follow a different PN-Serial Number combination indicating that they would have had to be printed as different starting position and most likely at different times.

This is also the case for several other prefixes in all denominations of this current series. I have noticed many incomplete runs and gaps.

Would you be able to share the specific prefixes where you have found similar situation?

I believe that CBN may have printed two serial number ranges for 540,000 GHD M-C notes. Under "Journey Series Mega Sequences" (see Wiki article http://wiki.cdnpapermoney.com/index.php?title=Journey_Series_Mega-Sequences  )

The low range is probably up to 0180000 and the higher range probably 4900999 to 4540999.

If CBN Layout 8 is reversed (or flipped vertically so that what was right is now left and vice versa/with position A3 the same):
1         2        3         4           5
A 0101     11 11  21 21   31 31    41 41
B 02 02    12 12  22 22   32 32    42 42
C 03 03    13 13  23 23   33 33    43 43
etc to row "I"
-this may account for the new PN pattern.

I am  not sure if the actual observed notes support the flipping of the position number matrix.

What they support is there were two separate runs with a distinct break in serial numbering. This has also been noticed with some other prefixes. One such example that I have recorded is HBV.
