Pin EDF0011 is the Supporters' Club pin. We believe this club is an internal promotion of the Games within EDF. We have no information on pin EDF0015 but given there is a star in the design, it is possibly some sort of award or recognition pin. EDF0011 is limited to 2,000 pieces and EDF0015 to 500.
Please remember these are internal pins and will not be issued to the public. EDF will not be responding to requests for these pins. EDF are one of the best sponsors for engaging with and supporting collectors and are happy to send out pins where they can, but these two will not be available.
