    take each individual coin's weight and multiply it by the grade, then divide by the total of weights in the set.

    Example: 1876 twenty cent set is composed of 1876 weight 3 grade 66 and 1876CC weight 10 grade 64. 3 X 66 = 198 + 10 X 64 = 640. 198 + 640 = 838. 838 divided by (3 +10) = 64.xx

    Don't forget to add any bonus before multiplying by the weight.
