The most valuable remains the blue Rivadavia (actually blue-green), with rubber on the reverse, 15 cents, undented from the year 1864.

Berdino Rivadavia was 1st President
of the United Provinces of the Rio de la Plata from 8 February 1826 to 27 June 1827.

Averaging the values in different catalogs, it runs around  21,400 pesos .
