Morgan dollars - which should I have professionally graded?

I'll start this post out with stating that I am new to coins. I have been looking at some grading videos and am reading the Red Book and other books but admit I know nothing about the worth of coins. After taking a quick inventory of all of the Morgans I have in old blue books (and a few in plastic holders), it looks like I have about 30 that, even in just good condition, might be worth a couple of hundred dollars each. They include an 1897O, an 1886O, and an 1896O. Question - how do I know which coins I should have professionally graded? All 30? And, how many appraisers should I go to? Thanks so much.

Don't clean the coins! Post photos here of a few and see what responses you get. There are many knowledgeable collectors and dealers on this forum who will give you good advice. Forget about "appraisers". Just buy a copy of the Guide Book of United States Coins and read it carefully.
Those 3 dates you mention are common dates that aren't worth significant money unless they are in about uncirculated condition not "good condition".
But, as others have said, pictures would help.
I hope the OP comes back with three photos of MS65 DMPL dollars. That would be a lot of fun with these three dates.
As stated above, we need photo's to help you. Start with just two or three, both sides. Were these an inheritance? Cheers, RickO
