    bonsoir,

    à mon avis c"est une pièce qui a trempé dans un liquide acide,et celui ci à enlevé la 1ere couche aluminium

    il y a + de 20 ans j'avais essayé de nettoyer des pièces en bronze alu par trempage dans du vinaigre et sel de mer et porté à ébullition ce qui donne de l'acide chlorhydrique et j'avais obtenu le même résultat que vous.......couche supérieure en grosse partie disparue

    voila !!!! à vous de voir.

    bonne soirée...

    cordialement;

    Ce n'est pas dans le domaine des monnaies, mais j'ai dernièrement traité un canon de pistolet ancien à l'acide chlorhydrique (ce qu'on appelle également "esprit de sel") pour le rendre plus mat...
    Si vous utilisez ce produit, attention aux vapeurs (toxiques) : ça fume et ça pique ! Et le métal est lentement "bouffé" par l'acide, couche après couche....
