These two used antique Watrous Manufacturing Co sterling coasters have a total weight of 2.185 troy ounces. They have a 2 5/8" diameter on the top rim and 2 1/2" diameter on the bottom and are 1/2 deep. Watrous Mfg Co was founded in 1898 and was one of the founding companies of International Silver. Condition: These used antique Watrous Mfg. Sterling coasters have a slight bend in the same spot on each rim where they were stacked together and they both show wear from use on the inside base. There is a tarnish spot on the rim of one of the coasters. I did not polish these.
