is NGC the only 3rd party grading service that will grade the coin in the original GSA holder?? and if Yes how can I submit just 2 coins, as a ANA member , NGC says I have to submit 5 GSA coins at a mininum for economy service.
Yes, NGC is the only service that will grade them in the GSA case. Unless you have three other coins to submit along with them, your only alternative would be to "piggy-back" your submission with another collector or a dealer. Chris
