Canada $20 Bank Note 1979 Cbn Or Babn?

This is a CBN note.

Cheers, Bill

There's a lot of information within the serial number alone for the issues of 1979
The serial number breaks down like this
5 - represents the denomination 5=$20
2 - indicates printer "0" or "2" denotes CBN, "6" denotes BABN (except for replacements where the third digit represents the printer).
5
8 The next two numbers 58 are the series number
5
6
7
9
8
7
1 And the last seven digits are your serial number

In conclusion the "5" tells me it's a twenty the "2" tells me the printer is CBN the 58 refers to series 58 and yours was the 5679871 note printed.
Hope this explains it better.

Cheers, Bill
