Mr. Frampton researched a lot for his book, using many new and interesting sources. His first edition has become a standard guide for researching about Mexican currency. The new book has six sections Imperial and early Republic; era of the private banks; pre-Revolutionary currency issued by entities other than banks; Revolutionary paper, including military, state, municipal, and private issues; emergency currency from the post-Revolutionary period; and early products of the Banco de Mexico, down to about 1970. Frampton invented two numbering systems for listing the notes which are followed by many collectors and researchers even today.
