Thomas Spence (June 21, 1750 – September 8, 1814) was the radical inventor of a system of land nationalization. He was born at Newcastle-on-Tyne, England, the son of a Scottish netmaker and shoemaker.

A dispute in connection with common land rights at Newcastle impelled him to the study of the land question. His scheme was not for land nationalization proper but for the establishment of self-contained parochial communities, in which rent paid to the corporation (wherein the absolute ownership of the land was vested) should be the only tax of any kind.

His pamphlet, The Meridian Sun of Liberty, which was first hawked in Newcastle, appeared in London in 1793; it was reissued by Mr. H. M. Hyndman under the title of The Nationalization of the Land in 1795 and 1882.

Spence presently left Newcastle for London, where he kept a book-stall in High Holborn. In 1794 he spent six months in Newgate gaol for the publication of a pamphlet distasteful to the authorities, and in 1801 he was sentenced to twelve months' imprisonment for seditious libel in connection with his pamphlet entitled The Restorer of Society to its Natural State. He died in London on 8 September 1814.

Spence issued many tokens with social and political themes but this particular example is simply an advertising token.
