  1. I have a couple of 1987 U.S. Constitution Silver & Gold 4 coin sets in mahogany cases and wonder if it's worthwhile to have these proof and uncirculated coins graded. Could they be graded as group or would they have to be separately graded and removed from case? If graded i presume the case would no longer be an option. I'd also like to know what the average grade NGC gives to US Mint proof coins. Any thoughts on US mint proofs vs NGC grading would be appreciated since I have a number of US mint proof coins that are not graded.
