Help Decyphering Sealed Box Canada 1965

I'm trying to catalog my accumulation and I found this:
It's sealed, and I'd rather not break the seal. It's between half and 3/4 of an inch thick. Does anyone have any idea what this might be?

you know you gotta open that now
I'm going to go with three of the 1965 proof like mint sets

Did the mint have any other products aside from prooflike sets in 1965?
Maybe they had basic uncirc sets? This was pre-product explosion it sounds like, and this (according to that random Coinworld article I googled) was the highest selling set. Without putting any more effort into it I would guess yes. I'm also guessing there are people here who actually know the answer though
eta: Maybe if the op edited and put Canada in the title the right eyeballs will show up. @daltex
I don't think the RCM sold sets like that.
That is an unopened box of RCM 1965 Mint Sets in the Pliofilm w/envelopes and cards. Probably 5 sets. You should open it as there is a nice variety Large Bead, Blunt 5 small cent to look for. Also, Deep Cam PL's are gaining traction.
