1987 US Constitution 4 coin gold and silver coins ($5 gold and $1 Silver commemoratives) in mahogany case 1 1

[SALEMJMC]

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.

Hello @SALEMJMC, 

Thank you for reaching out to us. Different collectors have different reasons for grading their coins and because of this NGC cannot provide guidance regarding whether grading these coins may be worthwhile for you. I can provide some information about the process, however. The coin set would not be graded as a set. Each coin would be graded and placed in an individual holder. You can submit the coins in the mahogany case and request that it be returned to you, but the case cannot be encapsulated. 

If you would like to view the grades for similar coins, the NGC Census provides information on the number of coins NGC has grade at each grade for different coin types: NGC Coin Census Population Report | NGC. 

If you are interested in grading your coins, be sure to read out how to submit guide here: How to Submit | NGC (ngccoin.com).

   In my opinion, you should enjoy these coins in their attractive case and avoid the substantial cost of having them certified by a grading service.  These are very common, high mintage early commemorative issues. They are already protected by their sealed capsules, and the original case and government certificates are evidence of their authenticity.   The only premiums much over bullion value per the NGC Price Guide are for coins graded "70", and it's not enough of a premium to warrant the expense. The odds are that yours would be graded "69". 

   I suspect that at some point in the future, collectors will regret that so many of these coins were removed from their original packaging, and the pieces still in them will be the ones worth a premium.  This is already the case for GSA Carson City and other silver dollars.
