'Set Rating' calculation

Can someone please explain how 'set rating' is calculated. I've noticed sets below my ranking that are higher in both '% Completed' and 'GPA Weighted.' Is it the date and mintmark combination?

(My set is a date-run set.)

    Pretty much what I suspected. I wish there was a table to determine the weighted value of a particular coin and grade combination. That would be one huge pdf file.



    What are weights? Within a set, not all coins have the same value and rarity. Sets in the PCGS Set Registry are weighted on a 1 to 10 scale with 10 being the rarest coin and 1 being the most common. While it may be in true in some instances that a coin may be many times over 10 as rare as the most common coin in the set, the Registry keeps the scale simple so that all levels of collectors can compete.



    The Registry weighting is done by taking three things into account:



    1. The overall rarity of the coin, i.e. the rarity in all grades



    2. The rarity in the highest 2 or 3 grades



    3. The price (because this is an indication of demand and importance to collectors)
