Cough, cough. Uh, yeah. If these are 1 oz liberties (which I think they were based on OP's discription), our other estimates are low by 4x. We're talking buy a house money in a MCOL area.
As for the can of old silver circulated coins: that can easily be over $1k, even as much as $4k, depending on the actual size of the can. This is just in metal value, ignoring possible rarities. Because they don't pack as well as smaller coins like dimes, they may not be worth as much. Dimes can be surprisingly valuable. And you said they were dollars? These need to be sorted and checked for numismatic value. If they are Morgans, they are always fun to check out. I saved a few of my Morgans cause I just like them. They are classic Americana.
OP: I think you know this, but proceed with caution here on multiple levels: theft, tax, value, etc. You have a nice surprise gift of a project from Dad.
