Octavian Luchian was one of those men who did not choose a career based on his hobbies, but rather based on what was needed for his country. Nevertheless, apart from his duties at work, many times impoverishing, he invested time and money in numismatics, an area opened for amateurs and professionals alike. During the interwar years, as he worked for the Romanian Railways, he traveled extensively throughout the country and collected numerous ancient and medieval coins. Those objects made one of the most important autochthonic numismatic collections, used for the writing of the first major work on the Romanian coins.
