"I am writing a complete new book on the tokens, especially the plantation tokens, issued in British North Borneo in the period of c. 1880 till 1924. As background I use our 2001 book on Plantation Tokens of the Netherlands East Indies and British North Borneo, edited and written in cooperation with Prof. L.T Wells jr. co-editor from Boston (USA) and the book of Saran Singh (Malaysia). I invite any collector of these tokens to contact me to exchange information about potentially new discoveries in these area. They can mail me at : lansenkil@hotmail.nl"

Can anyone help? Ad kindly provided images of the earlier book and an assortment of tokens as an example. -Editor
