Mexico 1714 Eight Escudos

I have a question. Where did this exceptional 1714 Mexico 8 escudos go? I know what it sold for at the Goldberg's Sale. I know what it sold for in February of 1967. All you could want is a little more GRAT.
Did you know there are five, not four, major varieties of the 1714 Mexican onza? An example of the neglected Rosetted shield and plain cross variety can be seen on my website.
