Farm tin

Farm tin or the tin dues was one of a number of payments required of tin miners in Devon and Cornwall.

The holder of a mining sett was required to pay a portion of the black tin extracted to the holder of the tin bounds in which the sett was granted.

The portion was the "farm tin".

[1] The portion was normally interpreted to be one-twelfth of extracted tin: they were also required to play toll tin, calculated at one fifteenth.
