AFDCS American First Day Cover Society

The American First Day Cover Society (AFDCS) is a volunteer non-profit and non-commerical organization serving the needs of First Day Cover collectors, cachetmakers, and dealers. Founded in 1955, the society has a membership of over 1,100 active first day cover collectors, including many who design and manufacture their own cacheted FDCs.

A First Day Cover (FDC) is an envelope or card bearing a stamp which is cancelled on the day the stamp is initially placed on sale by the postal authorities.
