I wonder if there's a statute on the $10 Wilkins-Macklem signature notes, now that the Rogers-Macklem signatures are out in full force for the $10s? Makes me wonder if there is a recall on any unreleased Wilkins-Macklem $10s to make way for the Rogers-Macklem $10s? Of course, if there is a recall, any existing $10s with older signatures already in circulation that are still in good condition wouldn't be affected.
Maybe that could explain the significant absence of FFJs issued into circulation, as well as FFGs over the 7 million range.
Also, I have noticed that, so far this year, October had no new prefixes reported to the SNDB. All other months this year have had at least one new prefix reported. HJD - the official last new Lane-Macklem prefix to ever be issued - was likely the last prefix legitimately reported, which was early in September (FLZ, said to have been reported late September, is most likely an error). Maybe there's a dry spell happening now.
