Hello.
New to the forum and basically new to Coin Collecting as well.
I got some silver dollars from my grandma a few days ago, and I had some questions.
The 3
Peace dollars appear to have wear on the reverse in the wording at the top on the pics, on the coins themselves they appear fine

#1 Has some shine, but not nearly as much as #3.

#2 Appears to have tape residue along the bottom of the obverse. The coin also has a goldish tint, assuming its just tarnish.

#3 appears to be in pretty good shape with quite a lot of shine. The pic shows almost like some scractches on the obverse, you cannot see that on the coin.

This is the best one out of the Morgans that I got. It has minimal shine left.

This one is dirtier than #4, has less shine, but still seems in good shape.

#6 Appears to have ink or something on it. Whenever it is held at an angle, you can see a deeper bluish/purplish shine around the edges.
First off, I was wondering some grades on these coins (which is why it is posted here).
Second, cleaning. Now I know people are very adamant on NEVER CLEANING A COIN, but #2 and #6 seem like they might need something. If people still say to never clean a coin after seeing these, then I will listen...
Third, is the shine also called luster?
Fourth, how can I post the pictures so they just appear and they don't have the little thing you gotta click on?
And I think that is all for now. I thank you all in advance for your help.
