-Yes, your right, guess I was still thinking about the actual scarce prefixes (BSW, FTH, GHD, etc) or had a brain fart.  HBG is the only prefix with M/C signatures. Thanks, I revised my post.

HBG also Mac-Pol.

HBZ note 85***** is Mac-Pol.

Are the HBZ's and HCA's both scarce?

Hi "russ." Welcome to CPMF.  The short answer is "no" as neither prefix is scarce. As of today (06/25/19) the SNDB reports that:
HBZ - 2,584 note entered & HCA - has 2,627 notes entered by various members of the CPMF.  Such high numbers suggest they're very common.  Since you have access to this forum- you will also have access to the "Serial Number DB" icon in between "Calendar" and "Logout" icons and you can check these figures for yourself.

As far as I can tell, from the SNDB data, there doesn't appear to be any scarce prefixes for the $5 polymer.  Below are the figures for the following Macklem-Poloz HCG/HCM prefixes.  Incidentally, the "HCG" thread you posted to was created because it appeared that the prefix was delayed in terms of its release.  To give some perspective, I have also copied down the M/P HCM change-over entry:
HCG -763
HCM -854

486 of the Wilkins/Poloz HCM prefixes have been entered.  Since it was released well after the first HCM I would not consider this change-over scarce either.  The $50 Macklem/Carney GHD has 52 entries and it has been out for 7 years. Since not as many members enter $50 notes I would just consider this prefix is a "tough" one to find (or uncommon) but not scarce. 

For M/C $10 FTH (13 entered) and the M/C $20 BSW (14) [or the M/C $50 AMK & $100 EHZ] it's a different story.  These prefixes have been out for around 7-8 years & their low numbers would suggest that few were released into circulation.

HCG 030****

if soaked long enough it can become detached.

Well if I remember correctly (I had a near death experience) these notes were way out of sequence with the consecutives in the bricks 97's and 96's, so i kept them.

Welcome Russ.

This is interesting indeed: can you tell us about more about the brick sequence and what prefix they were found with?

Just to clarify, these serial numbers are not listed as confirmed insert ranges.  Having said this, unless there are alot of members who come forward saying they found these ranges, it will probably never be considered a sheet insert range.

Looking forward to your response

5 mac-pol SNR HBG 7822400-599 

I have several(10) mac-pol HBG series but the 98's might be replacements:



9818249
9817249
9818049
9818849

also have HBG 9702846

These were from bricks years ago. Any information from the pros on this forum?
