The Token Book Volume 1 by Paul and Bente Withers of Galata Publishing.
Upon release this book very quickly became the go to reference work for collectors and dealers alike. A seminal work that attempts to draw together the vast array of British pieces in this collecting area.
Now out of print and extremely difficult to obtain.
Hardback with 512 pages. Excellent condition, appears to be unused although the corners are indented (probably from being dropped).
