Collector's Set Honors Heroes and Victims of 9/11 – Your Choice of Single Stamps or Silk First Day Covers
Today you can get two stamps issued in memory of September 11, 2001. The stamps feature an iconic image of first responders raising the American flag over Ground Zero plus the "United We Stand" American flag stamp.
US #B2 is a Semi-postal stamp that sold for 45¢, with 11¢ of that going toward a fund for families of first responders killed or permanently disabled in the 9/11 attacks. It raised $6.5 million in all.
US #3549 was issued just one month after 9/11 and includes the words "United We Stand," to remind the world of the purpose, pride, and determination that makes America one of the strongest countries in the world. This famous phrase also recognizes the countries around the world who stood with us on 9/11 and continue to stand against the threat of terrorism today.
