التمييز بين عيارات الذهب (Info)
يمكن التمييز بين عيارات الذهب المختلفة بسهولة عن طريق النظر إلى الدمغة التي يختم بها المصاغ الذهبي، فمثلاً يحمل مصاغ عيار 24 مربعاُ فيه الرقم 1000 أو 24، ويحمل مضاغ عيار 21 الرقم 875 أو 21، ومصاغ عيار 18 الرقم 750 أو 18، وهكذا، وكذلك يمكن التمييز التقريبي بين العيارات من خلال النظر، فكلّما مال لون السبيكة للشحوب، دلَّ ذلك على أنَّ نسبة الذهب فيها أقل.
