Because postage stamps are truly a matter of trust, Zumstein & Cie has gained a very good reputation across the globe. There's not one of the major Swiss rarities – from the block of fifteen "Basel Doves", the thirtythree "Winterthurs", or the block of "Double Genevas" – that hasn't once passed through the hands of the Zumstein company. Zumstein offers security: At our world-renowned expertising unit, expensive stamps are checked prior to sale and awarded a Zumstein certificate as a guarantee of authenticity.
