In the book there are photos of all the different types of square coins, descriptions, weight, mintage, metal composition and when possible also information about the design and designer of the coins. Also it has some new information that has not been published before in any catalogue. Such as the mintage of the 25 Ghirs of Sudan. Variations for the 1966 square coins of Suriname and even coins that are not in any other Catalogue such as the 5 Poisha from Bangladesh 1978.
During my research I did get a small grant from the Central States Numismatic Society and it is because of this that I can offer the book cheap to members of Numista and other coin clubs and Libraries.
Member price 4 us plus 6 us postage, and more books is less postage cost.

If you are interested send me a PM and i will send my email address
If you consider writing a book about coins and want some advice ( how to survive and stay mentally healthy, do write to me I may have a few tips )
