i am way to new to notice the imperfections...

that appeir when a coin is cleaned. i know only 1 thing that if they use a rough item to clean it will show extra "hair bunches" like if you use a brillo pad on a pan. but what am i looking for if it has been dipped and other forms of cleaning. i have many coin books but none that explain or picture a cleaned coin. this is a big issue only on the full sets i have ae: peace dollar and morgans.

is there a good book with photos and close ups on what to look for?

and again thank you all for helping the new guy:) it is appreciated.
