Is it better to sell my silver dollars to a local dealer or at a coin show?

I bought seven rolls of 20 coins each as an investment in the early 1980’s. They have generally been a bad investment, but the values have gone up recently. I would like to sell. Which is the wiser course – – selling to a local dealer or at a local coin show (which is coming up in two months)? Some other way? I don’t want to sell on eBay.

For the record, this is what I have:

1 roll 1884-0 pretty darn close to “Brilliant Uncirculated”
1 roll 1921 Morgan – close to “Almost Uncirculated”
3 rolls 1921 Morgan – noticeably below AU but still have very good definition in the hair strands
1 roll 1922 Peace – like the prior roll, it is definitely not AU but also shows no obvious or major wear; also some seem to be dirtier than you’d expect for so little wear
1 roll 1923 Peace – same as immediately above

I’m not a serious coin collector, although I enjoy coins.

Does anyone have an educated guess as to what the coins might be worth?

Thank you very much for any help you can give me!
