10 Roubles First intercontinental flight

Pridnestrovie — the unrecognized breakaway state on Moldova's eastern border — has produced commemorative silver since the early 2000s, issuing coins that circulate internationally among thematic collectors far more than they ever do domestically. This piece marks the centenary of the first intercontinental flight, completed in 1924 when a Portuguese crew under Gago Coutinho and Sacadura Cabral's earlier pioneering work was followed by the first true multi-leg intercontinental crossing linking Lisbon to Macau by the Portuguese Aero Club team — though collectors should note the precise flight commemorated here warrants verification against the issuer's documentation, as Transnistrian commemorative programs occasionally apply "first" designations loosely.
