All-Time Finest category
The Registry is divided into two sections. The first section, the All-Time Finest (ATF), ranks all current and retired sets.  Retired sets remain in the Registry if they are at least 90% complete.

Current category
Registered sets in this section are sets that have not been retired and are actively being updated by their owners.

Bonus points and deductions
Some sets may have bonus points assigned to certain items within a set. 

Certification number
 
The certification number is unique 7 or 8-digit number placed on the the item or on the Letter of Authenticity.  This number can be used as a reliable means of identification after the PSA/DNA autograph or memorabilia has been graded and re-enters the marketplace.  

Grade Point Average

The GPA is the grade of each item registered in the set multiplied by the weight and then summed.  That sum is divided by the total number of the weights of the registered items.

My Set Registry
The private administration pages in the PSA/DNA Set Registry where members log in and add, update, and delete their items and sets.

Sports Market Report
The SMR is a guide to assist the card buying public in determining values for most significant sportscards, tickets and memorabilia. The prices listed in the SMR are the average dealer asking prices for properly graded items. Prices listed in the SMR are based on recent sale prices of Professional Sports Authenticator (PSA) graded sports cards and PSA/DNA autographs and memorabilia. Prices for the most actively traded items are updated regularly. Other issues are updated as needed.  To access the free SMR Online, click here. To subscribe to the printed version, click here.

Pedigree
A listing of an item's current owner plus previous owners who may have had significant collections.  Pedigrees are sometimes printed on the insert of a sports card which has been graded.

Set Composite
The items contained within a specific set.

Set Rating
The Set Rating is achieved by dividing the weighted grade sum by the total sum of the weights in the entire set.

Weights
Within a set, not all cards and tickets have the same value.  Sets in the PSA/DNA Set Registry are weighted on a 1 to 10 scale with 10 being the rarest item and 1 being the most common.  While it may be in true in some instances that an item may be many times over 10 as rare as the most common item in the set, the Registry keeps the scale simple so that all levels of collectors can compete.  Each item within the set is assigned a weight based on the value of the item in NM-MT condition.
