Explanation: I have NO idea of "contraste", but just think, in those days two people were the most important characters in religious art: the donor and the maker.
In fact, before the 15th century in Spain (particularly in Catalonia) the sculptors were usually Sephardic Jews... too unclean to sign, I guess. (This is only in Spain, further North they weren't allowed to touch religious art by the guilds, but religious artists in Spain had a low enough station before the Baroque period).

Explanation: "Fiel, fiel contraste: Cofrade responsable de la ley y calidad del trabajo en las piezas dentro del gremio de los plateros. Hasta el s. XVIII marcaba las piezas con el punzón del fiel contraste, que llevaba su nombre y era distinto del que utilizaba como platero. En algunas ciudades era obligatorio que este punzón llevase además las dos últimas cifras del año."
