Canada 1948 & 1953 year set question

Does anybody know anything (where/when/etc.) about how these sets were packaged? The 1948 set is in a black cardboard holder with mylar slides on both sides (like Dansco albiums). The 1953 set is in a white cardboard holder, wrapped tight with cellophane.

<< <i>Isn't that original packaging on the '53 set? >>
I just checked the Charlton catalog- the '53 looks like the picture under "Proof-like and Brilliant Uncirculated Sets"- there is no price listing for 1953 sets, but it does say that "1953 saw the first use of the white cardboard six-coin holder", so it looks like that's what these might be. The '48 set does look like an aftermarket type holder- I have a second set in a similar holder that only has the 1c through 50c, with no space for a dollar coin.
