Lowsley #Unlisted Pridmore #115

Obverse : obverse or reverse of coin which is countermarked TC (incuse).
sometimes the Counter Marked coin face has been erased.
Reverse : obverse or reverse of coin which was not countermarked.

See also a speculation posted in an auction repeated by PCGS says that these pieces could have been the work of Tatham & Co from Sudduwelle Mills, a firm that issued its own token coinage listed in Pridmore as reference #102. The company fell under Christopher Tatham as sole proprietor in 1861, which would fit the date range estimated by Pridmore for such pieces. The TC could stand for "Tatham & Co" or "Tatham Colombo".
