Here’s a genuinely fun, versatile and complex modern stamp series that I’m sure most stamp collectors are blissfully unaware of. In 1991 Philippine Postal Service launched a new definitive series that was made out of very small sized stamps (about a third of regular commemorative stamp size in order to save on production costs) repeating floral topics in varying colors (again, to save on production costs). All major catalogs state there’s nothing more than 42 face different stamps in varying colors and values issued within 1991 and 1992 . But when one starts piling up copies and comparing duplicates against each other, it becomes evident that major catalogs are likely telling a partial truth. And when looking into more specialized resources, the genie comes out of the bottle: instead of 42 stamps there are at least 98 major varieties in this series.
