I am considering joining NGC Premium membership for $125/year. The Premium membership gets you a coupon for 5 free submissions of Early Bird, Standard World or Ancient Standard submissions. I want to submit a mix of two China Silver Pandas, one USA Dolley Madison gold, one USA Trade Dollar, one USA Morgan Dollar. Will that coupon cover that variety of coins? Can coins be submitted in a mylar flip. NGC's instructions are rather sparse.
I do not know the answers to your questions, but if I were you I would call their customer support line. They are VERY helpful. 1-800-ngc-coin.
At least a few years ago, the coupon required that all the coins be sumitted be in the same group; e.g., either world, US, or Ancients. One could NOT mix the groups. I've always submitted my coins in a Mylar flap. guy
Yes, any safe slips are fine. If you submit a coin in a 2 x 2 stapled, or air-tite you risk a $1 removal fee.
