The American Helvetia Philatelic Society (AHPS) is the largest group of collectors of Swiss stamps outside Switzerland. The current organization dates from 1975 but traces its lineage to 1938, when six Swiss and three Americans founded the original Society for Collectors of Switzerland in Philadelphia.
Today the AHPS offers a full range of services to some 200+ collectors and researchers located primarily in the United States, but also in Canada, Great Britain and Switzerland. Interests range from new issues, rarer stamps, errors, cancels, postal history research, and international exhibitions.
