San Marino – Arturo Toscanini – 5 Euro – 2007 – Proof Silver Crown – Case & COA Arturo Toscanini (March 25, 1867 – January 16, 1957) was an Italian musician. He was considered by many critics, fellow musicians, and much of the classical listening audience to have been one of the greatest conductors of all time. He was renowned for his brilliant intensity, his restless perfectionism, his phenomenal ear for orchestral detail and sonority, and his photographic memory which gave him extraordinary command over a vast repertoire of orchestral and operatic works, and allowed him to correct mistakes in orchestral parts unnoticed by his colleagues for decades.
