Can anyone tell me if you can mix and match the "5 coin minimum" among the required minimum grading tiers with an NGC submittal (ie. 3-Morgans, 1-Foreign gold coin, 1-world coin) or do you have to have a "5-coin minimum) per tier?
I believe it is mix-n-match. Call them first, but I don't think they are concerned about various denominations and coins, just the minimum number.
