I wrote an article on the 1949 Mexico Restrikes in 2006 and put it on my website (below).
Some were made in Mexico City and 2,000,000 were made in San Francisco.
I found the above referenced The Numismatist
It is in the July 2010 issue and is entitled
"Striking Pieces Of Eight At The San Francisco Mint" by Gerard Muhl.
It can be found at:http://digital.ipcprintservices.com...hp?id=424354
The article is mostly a history of Mexican coins used in America and
the attempt to set up a Mexican mint in San Francisco.
