50 Lei COANDA-1910

This piece is one in a series of Romanian commemoratives honoring figures from the history of aviation and technology. Henri Coandă, the subject of the 1910 date referenced in the issue title, claimed late in his life to have built and flown a jet-powered aircraft in Paris in 1910 — decades before the acknowledged development of jet propulsion. The claim has never been substantiated by contemporary documentation, and most aviation historians treat it with considerable skepticism.

Romania nonetheless embraced Coandă as a national scientific hero, and the Banca Națională issued this coin firmly within that patriotic tradition rather than the historical one.
