5 Reichsmark Graf Zeppelin

Issued to commemorate the Graf Zeppelin's 1929 world circumnavigation, this coin was authorized by the Weimar government at a moment when the airship program represented one of the few unambiguous sources of national pride available to a politically fractured republic. The voyage — completed in just under 21 days — was partly financed through philatelic revenue, with special mail carried aboard the LZ 127 sold to collectors worldwide.

The .500 fine silver content reflects Weimar-era treasury constraints rather than any minting preference. Struck at Berlin, the issue saw wide circulation and fully worn examples are far more common than the mintage figures alone would suggest.
