I received my new 20th Edition this morning. I haven't had time to go through it in detail but my initial impressions are exceedingly favourable. It cost me CDN$30.00 from CharltonStandards on eBay, inclusive of Express Post shipping.
As we expected, a lot more attention has been devoted to modern (post-1969) Bank of Canada issues and there is extensive coverage of the new definitions of the "uncirculated" grades , i.e., GEM UNC (GCU65), CHOICE UNC (CHCU63) and UNC (CU60).
I personally prefer Charlton's three clearly-defined grades of UNC to the complicated numerical "sliding" scale (MS-60, 62, 63, 64, 65, 66, 67, 68, 69 & 70) favoured by the commercial US grading companies. The numerical scale is just too complicated and prone to inconsistency in my opinion. For example, what is the
real difference
(in unambiguous words) between an UNC-60, an UNC-63, an UNC-65, an UNC-66, an UNC-67, etc.??
What I find particularly satisfying and refreshing about the new Charlton Unc grade definitions is that for a note to be GEM UNC (GCU65), CHOICE UNC (CHCU63) or just plain UNC (CU60), it must be ENTIRELY ORIGINAL, and I quote
"The note must not be processed or pressed". In other words, any note that has been processed, washed or pressed can never be any better than an AU (ABOUT UNC) at the very best. Unfortunately, many washed and pressed notes will continue to be described as "uncirculated" because some buyers and sellers are unable (or perhaps unwilling?) to distinguish between a pressed note and an unpressed note. That's why, in my humble opinion, it behooves all collectors and dealers to learn how to grade properly themselves and not to rely solely on the so-called "professional" graders who are not always better at grading than you or I.
And before I forget, the new Charlton catalogue carries a superb new section entitled "PROCESSED NOTES" (containing valuable insight concerning the many rare notes that have been ruined over the years by processing) and a revised section entitled "GRADING NOTES". We will all be able to learn something new from these two valuable sections.
The only thing I have some difficulty with is the statement that a GEM UNC note is
"A near perfect original note". This suggests to me that a GEM UNC note is not necessarily a "perfect" note, which leaves the door open for a SUPER GEM UNC grade! Oh No!!
All in all, however, the 20th Edition Charlton Catalogue is a truly superb piece of work!
