Gold Ecu with sun - Francis I 2nd type, 3rd issue, Turin

Francis I standardized the écu au soleil through a series of royal ordinances, with the 1519 and 1519-onward reforms attempting to stabilize gold coinage against the chronic underweighting that had plagued French mints for decades. The Turin mint — operating from the Piedmontese capital following French occupation of Savoy in 1536 — was among the last authorized to strike this type, and its output was modest. Francis held Turin only until 1559, making the window for coinage there narrow.

The Dy 771A attribution places this firmly among the scarcer provincial issues of the series.
