Le May, Reginald, The Coinage of Siam, Originally published by The Siam Society, Bangkok, 1932, reprinted in Siamese Coins and Tokens, Andrew Publishing Company, London, 1977, 389 pages including plates, hardcover. The first comprehensive study of bullet coinage of Thailand, both Ayuthian and Bangkok. Still the most useful primary reference on the series. Includes blocks with line drawings of the different marks found on the coins. There are mediocre photos of many of the bullets and a few other primitive type coins. The only real drawback is that there is not a system of assigning catalogue numbers, ex James Farr Collection Library.
