Antique knife with holster

Sorry, I am unable to upload other photos.

I think yours is like this one https://www.worthpoint.com/worthopedia/antique-greek-ceremonial-knife-51977995 The dagger was probably made in 1921 to commemorate the 100th anniversary of the beginning of the Greek War of Independence which officially began March 17, 1821 and ended in 1830. There’s quite a few at worth point with a search of Greek Dagger 1821 https://www.worthpoint.com/inventory/search?query=Greek+dagger+1821&categories= Those may be worth looking through to find more info.
