1. pg. 267 has a couple spelling mistakes in the "Caution! Asterisks are being faked" section. In the second sentence "deliberately" and "create" are misspelled. It appears to have been that way at least back to 2016.
2. The listed URL's on pg. xvi for BCS and CCCS appear to be invalid. BCS currently appears to be
www.banknotecertification.com, and CCCS currently appears to be
www.canadiancoincertification.com.
3. pg. 263 lists BC-41b ($20 Modified) prefix G/W as having a total of 8.8M notes printed. pg. 254 agrees with this number, listing the range as #1 through #8,799,999. However, going through my collection, I noticed I have note G/W 8999400. From what I can tell, these numbers go back at least to 2016. Am I misinterpreting something, or is the range actually larger than previously thought?
