Danish, Customs Seal, Mikko Tammelin.
Found in Finland, ?mm.
Crowned monogram of Christian IX // TOLD / PLOMBE, [KJØB]ENHA[V]NS around
From Paul Cannon, "I think this is a Danish customs seal. It has the monogram of Christian IX. The other face reads [KJØB]ENHA[V]NS around TOLD PLOMBE ie Copenhagens custom seal. Christian IX was King of Denmark from 1863 to 1906. This is the old spelling of Copenhagen. For similar (but different) Copenhagen custom seals see BSG.BS.01393 and BSG.BS.00475."
