This is a bit of advice about the coins, so I hope it helps. If some of this is not new knowledge to you, apologies, just not sure how much you know about coins.
Half dollars: Any Half Dollar post-1970 is clad, only worth face value. 1965-1970 are 40% silver, 1964 earlier are 90% silver.
Quarters and dimes: 1965-present are clad, only worth face value. 1964 and older are 90% silver.
Nickels: 1942-1945 are 35% silver (sometimes called War Nickels, since nickel was needed for WWII), others are typically worth face value.
Cents: 1959 and newer are worth face value. For the most part, 1940-1958 are worth face value. SOME pre-1940 MIGHT be worth more, but maybe a few cents each.
There are always exceptions such as key date coins (for example, 1950-D Jefferson Nickels), or especially old coins (roughly 1920s or earlier). If you are seeing mostly post-1940 coins, it might not be worth your time trying to search through them all, especially piles of circulated coins. Other exceptions to the above would be coins still in proof or mint sets. They are not worth much, especially anything 1960 or newer.
For anything clad/face value, I’d round all that up and take it to a local bank with coin counting machine. Call ahead and make sure they have one. Putting that amount of coins into rolls wouldn’t be worth your time.
For anything silver, here’s a guide to give you an approximation on value. Remember, when you sell to a dealer, they need to make a profit, so their bid will be a little less per coin or ounce than what is shown. Call up a shop and ask what their buy prices are for 90% circulated silver.

For any foreign coins, unless they have silver or gold in them, they won't be worth much of anything. Exceptions might be for coins from about 1920s and earlier, but even less likely than for your US coins. A lot of times people sell circulated foreign coins by the pound on eBay.
I’m sure this doesn’t cover everything you have, but hope it’s a start at least.
