How any bagpipe stamps are there?

The number of bagpipe stamps varies by country and collector interest. Various postal authorities have issued bagpipe-themed stamps over the years, particularly in Scotland, where the instrument is culturally significant. However, there isn't a definitive count of all bagpipe stamps globally, as new issues may arise and collectors may have different catalogs. For an accurate number, one would need to consult philatelic resources or databases specific to stamp collecting.
