To most collectors,the main appeal of collecting paper money lies in its lucrativeness. To me, however, curreccy collection is a way to secure scientific and artistic enjoyment,catch a glimpse of the humanistic and historical knowledge of different nations of the world, as well as broaden my horizons and elevate my spirit. As yet, I have collected and studied paper money from many countries and categorized and compiled them into my three favorite themes "Music","Art" and 'Human Life" to share with you.
