TL;DR I have some coins that I got from my mom. She doesn't care what I do with them. Started going through them and there are some things that aren't worth much of anything (1972 penny from Denver) to around 30 Morgan silver dollars.
A friend at church is a coin guy and has offered a trade for some noise tools in exchange for some coins. He's not trying to stiff me, but I want to see if I am seeing the value of these things right.
I've got all the coins of note cataloged, and I generally went to the lower end of what grade I thought things were.
TIA,
Jake
If you're inclined to spend some time at this, get The Blue Book and price them out.

The Blue Book is a guide to dealer buying prices, where the Red Book is retail selling prices.
Even rare pennies are unlikely to be worth more than a few dollars, but if you've got a number of Morgan dollars and other silver coins, it may be worth your time to price each one. A rare date or two could be worth as much as the rest of them combined.
Unless you need the money, consider sitting on them and passing them to your grandkids.
