Here is what I saw on the website:
Received
The submitted cards have been counted and entered in CSG’s computer system along with the submitter information, submission date and requested service(s).
In the next step, a detailed description of each card will be entered in CSG’s computer system (a process commonly called “verification”). The cards will be separated from any paperwork that would identify the submitter and the submission will be prepared for grading.
Scheduled for Grading
Each card has now been described in detail in CSG’s computer system and checked against the submitter’s descriptions. A unique identification number has been assigned to each card. These identification numbers are printed on temporary holders and will be used to track each card throughout CSG’s grading process.
Submissions are then arranged by service and received date so that they can be graded on a "first in-first out" basis by service level.
Grading / Encapsulation / Imaging
Cards are authenticated, graded and encapsulated. Once encapsulated, they are re-examined to verify that the grade and accompanying description are correct. The holder is also checked for defects such as scuffs or nicks.
After grading and encapsulation, cards are imaged.
Quality Control / Finalized
Cards are inspected and approved in Quality Control before being carefully packaged to return to the submitter.
Shipped
Cards have been certified, imaged, inspected and approved in Quality Control, carefully packaged and are being shipped back to the submitter. Grades and card details are now available for viewing online.
