We understand that some of the Paralympic Gold Medal stamps were sold out before they were taken off sale at the end of December.
As reported, the arrangement between Royal Mail and the International Olympic Committee ran from 1 January 2009 to 31 December 2012, and there was a flurry of orders to Tallents House before the cut-off date, which of course coincided with the Christmas/New Year holiday.
It's reported that some orders could not be fulfilled due to stocks of one or more sheets of Paralympic Gold Medal Stamps (containing stamps for 4 different medal winners) being already exhausted.
This suggests that the Paralympic stamps may be more scarce than the Olympic. We know someone who has access to competition mailings who has completed many sets of Olympic GM stamps on cover, but is struggling to find a single complete set of Paralympic GM stamps.
