The postage stamps of the Free City of Hamburg, issued between 1859 and 1864, are among the most historically significant and valuable philatelic items from the German states. Hamburg, a prosperous city-state, was one of the many independent German states that issued its own stamps before the unification of Germany in 1871.

The first series of Hamburg stamps was issued on January 1, 1859. These stamps are notable for their distinctive design featuring the coat of arms of Hamburg, a three-towered castle. The stamps were primarily issued for domestic use and reflected the city’s long-standing status as a major commercial hub and free port in northern Europe. They came in various denominations, ranging from ½ schilling to 9 schillings, with the most common values being 1, 2, and 3 schillings.

One of the unique aspects of these stamps is their simple yet elegant design. Unlike some other German states' stamps of the period, Hamburg’s stamps did not bear any portraits or elaborate decorations, opting instead for a straightforward emblem of civic pride. The color schemes were functional, making it easier for users to identify different denominations. For example, the 1 schilling stamp was printed in blue, while the 3 schilling stamp was a distinct shade of green.

These stamps were produced using the typography printing method, which adds to their rarity and value among collectors. Due to the limited print runs and the fact that they were in circulation for a relatively short time, many of these early Hamburg stamps are highly sought after by philatelists. Among the rarest is the 9 schilling stamp, which, due to its high face value, was seldom used and is now a prized item.

Hamburg ceased issuing its own stamps in 1868 when it became part of the North German Confederation. However, the stamps issued between 1859 and 1864 remain highly valued today, not only for their historical significance but also for their beauty and rarity, making them a treasured part of any serious collection of classic stamps.
