I agree with you the A/H and A/J probably do not exist , but they are in charlton. I have the confirmation from the bank of Canada ,that they do not have any copy in their files. In addition I sent a email to steven Bell the editor of charlton asking him to remove those two notes from the book.
about s/r 0.32-0.40 and s/r 0.64 -0.72
during the testing they changed the type of paper or the coating or other specs of the note
and s/r 0.32-0.40 was the test# 7 ; "to be printed faces last"
the s/r 0.64-0.72 was the test #10; "coated with urethan"
