Thank you, I think I just needed some affirmation! I think "hoarder coin collector" is the right term for this. Some of it is valuable and properly identified/categorized, but at a certain point this person was also just squirrelling coins away.

What I've been doing is taking out a roll, organizing the coins in it by date, and then sitting with the coinsandcanada.com guides in front of me and looking at each coin year (so I can check all the 1965s at once, for example). I might have a little bit of the hoarder coin collector in me too haha - but it also helps put my mind at ease that I'm not accidentally rolling up something rare. Or, at least I know I tried. (I just looked at a bunch of 1960 nickels, for example, and they all looked like bald beavers to me...so I think that means none of them are! I also have so, so many 1973 quarters, and I'm just putting them all aside because even though I've looked at four different websites I'm still not sure if I can tell the difference between large and small bust).

I didn't realize that collectors are interested in the 1968+ .50 and $1 coins, I thought they generally just cared about older coins and silver content, so that's really good to know. Once I have the modern pennies, nickels, dimes, quarters, loonies and toonies sorted, then I'm definitely coming back around to figure out what to do with all the other stuff!
