I received this email from PCGS today:
New PCGS Bulk Submission Policies Effective July 1, 2008
BULK SUBMISSIONS
Effective July 1, 2008, only PCGS Authorized Dealers may submit coins under the Bulk Submissions program. Collectors Club members who wish to submit coins under the Bulk Submissions program must either become a PCGS Authorized Dealer or submit coins through a PCGS Authorized Dealer.
SPECIAL INSERTS
Effective July 1, 2008, special inserts (First Strike, 50 States Flags, Signature Series, Satin Finish, etc.) will be available only through the Bulk Submissions program and will not be available under any other service level.
These changes are being made to speed up and streamline processing and turnaround times at PCGS. Any bulk submissions received by PCGS or postmarked before July 1 will be processed under the old Bulk Submission program rules.
