I really don't get it. I have a set weight of 15.16. I added a 1932 MS64 RD, 1940-S MS66RD, upgraded my 1943 from 64 to 66 and I went from 14.53 to 15.16. My GPA is 67.6. I really can not figure out the way this is set up. I look at the weighting sheet with bonuns for RD but its wierd math. What is the formula?

    It's grade + Bonus points x weighting factor = adjusted weight points

    1932 MS-64

    Grade 64 + (Points for Red) 2 = 66 x (weighting factor) 3 = 198 weighted points

    Ok so what do you do with the 198 Points? Is this added up for all the coins and then divided?

    It's extraordinarily simple, just get one of these and it will all become clear.

    Clackamas - After you add the bonus points to your coins and then multiply by the weighting for each coin you have devide the total by the total weights of the coins you have for your weighted GPA of the coins you have. If you want the Weighted average for your set in the Registry you devide the total of weighted points by the total number of weights in the set. I hope I havnt confused you more than you already are.

    I guess I was not clear enough. You got me most of the way but how is the set rating determined? I still dont have the other math down but I am getting there. I am trying to keep a spreadsheet on it.

    I figured it out. Thanks, all I guess it would help to fully read the web site.
