H A (Bert) Seaby and P Alan Rayner.  HB.  1968. 3rd ed. 203pp Illustr. 135 x 215mm

Standard reference on English silver coins listing all known varieties, major and minor.  Mintage figures where known, and rarities for each variety. 

Nice clean copy with d/j.  The above illustration is probably the worst of half a dozen in stock.  You will probably get a nicer one.
