4.5x2" unsure of the age or type of metal.  If you know, please message me.  I have cleaned it and it looks the same.  Patina.  Rounded bottom.  There are 4 Etched Buddhas.  Weighs 495gr s9 very heavy.  The other is hammered brass 3.5" and 175gr.  See pics for condition.  I have not tried to clean that one either.
