grading questions ?????

TROUT70

i am new to collecting and i would like to know what are the different grading services where you can get a coin graded and which ones are considered to be the top of the line or most respected because i have a few graded coins by different services and i have had a few fellow board members tell me what i had was worthless because of who it was graded by and is there any more free online price guides you can use . thank you

You'd be better off posting on the US Coin forum--you'll get a much better response
