Tracking The Million-Dollar Mistakes on Earth-Menzies

This is the splash page to The Million-Dollar Mistake, first published in Superman #102, January 1956. This story was published in Australia (aka Earth-Menzies) as The Million-Pound Mistake in Century The 100-Page Comic Monthly #1 c.July 1956:

K.G. Murray reprinted this story as The Million-Dollar Mistake in Wonder Comic Monthly #36 c.April 1968:

The similarly titled The Million Dollar Mistakes! was originally published in Superman's Pal, Jimmy Olsen #39, September 1959:

This story was published as The Million-Pound Mistakes! on Earth-Menzies in Super Adventure Comic #1, c.July 1960:

I am not aware of an Australian printing of The Million-Dollar Mistakes!, and given the GCD does not list a reprinting of the story before Showcase Presents: Superman Family #3 in 2009, I'm going to assume there isn't one. 

Having said that, there is no GCD listing for The Million-Dollar Mistake c.1968 and yet there is a reprinting in Wonder Comic Monthly #36. This may have been a case of the Murray editors amending inventory rather than publishing new material from DC, and if so, this would constitute precedent for a similarly reconsidered printing of The Million-Dollar Mistakes!.
