fyi: Making Money at the Banco de México Just wanted to share this after doing some online reading about Mexican banknotes. The Bank of Mexico web site has this interesting YouTube video which goes inside their operations to show how their currency is produced. Spanish only, but they show the entire process from design, security issues, production, quality control, distribution... Their web site has a lot of other interesting video, PDFs, links and various related information as well, whether you are fluent in Spanish and can navigate it well or just want to hunt around to discover things. +++ In the event any coin folks read this, the Mint site is here: Casa de Moneda de México
