  The "metallic" temperature variation of the electrical resistivity of
chemical nano gold-silver coatings with a silver content of 6.6 % at. up to
13.1 % at. determined in the temperature range 4.2-300 K. Features of
low-temperature measurements of the resistance of nano-coatings were found and
explained. The possibility of the appearance of superconductivity in them is
discussed.
