T576. Kinko tsuba with stamped flowers. 6.3 x 6.7 x .4 cm on the raised rim (less than .2 cm on the plate). The nakago hitsu-ana is .8 x 2.5 cm.  I don’t know which alloy this is made of; it isn’t shakudo and it doesn’t look like shibuichi either. Maybe we can call it yamagane (native copper) with a patina. Condition is excellent. $120.
