As you may be aware, the important factors for ranking sets in the PCGS registry are the weighted GPA (grade point average) and completeness of the set. Each coin is given a weight from 1 to 10 with the highest weights going to the rarest and most valuable coins. The grade of the coin is multiplied by the weight; then the sum of (weight x grade) is divided by the sum of the weights to obtain the weighted GPA. In some cases, bonuses or deductions are applied to the grade before weighting. To account for completeness or lack thereof, the sum of (weight x grade) is divided by the maximum possible sum of weights to obtain the set scores. Set scores are used for ranking sets. The registry lists the grade of each coin, the weighted GPA of the whole set and the set score. However, I have been unable to find a list of the weights for each type of set. I've searched the PCGS website and elsewhere without success. Does anyone know where the weights are listed for each type of set or is this something PCGS tries to keep to itself? Cal
I'm not much of a "PCGS guy" and even less of a "registry guy", but isn't that prominent on their website? If not, I am amazed. I forget in which subject the discussion was, but someone once said, "if you were playing a game, but you didn't know the rules, or how to score, and someone just told you when you scored, you wouldn't want to play, right?" I guess whoever said that isn't working on a PCGS registry set, huh?
I didn’t read all the posts in the PCGS RegistryForum but the answer to your question is probably in there somewhere. https://forums.collectors.com/search?Page=p1&Search=Registry+weighting
OK. I found it! Go to the first website page of the set type (the page that lists current sets and all time best sets). At the top, click on the link that states "View Set Composition"; it's just above the "Shop" button. The weights will be listed. Cal
