If your LCS is worth anything, they'll look at the coins you want to submit and give you further guidance as to which ones you should and shouldn't send.
He will tell me not to send any of them, but I grade my sentimental pieces. Coins I don’t plan to sell. A few coins I got gifted, a few I pulled from my first CRH, and a couple my best friend pulled from circulation for me. I love the holders, the feel, look of a graded coin. I get it from a monetary standpoint but we all collect differently!
