The best companies to grade coins are PCGS and NGC. If you were to submit, you would first need to pay for a membership or submit through a dealer. For coins under $300 value submitted under economy grading, it will cost about $25 to $30 dollars per coin. If your coin graded at AU53, the grading would cost more than the coin value. On a common Morgan my rule is that the coin must look at least MS63 or I will not submit. A lot of collectors want the common Morgan to be at least MS64.
