A nice "as struck" AU/Unc. piece with original toning. All of these types were struck over other crown-sized silver coins. This one was probably struck over a Spanish colonial 8 Reales. Nice buy for $35.
Are these usually weakly struck? The strike on this seems quite uneven. Not being terribly familiar with these, there seems to be some wear on the reverse. I'd call it AU at best.
"B" or Bahia Mint coins of this type seem to be a bit more weakly struck than the "R" or Rio de Janiero ones. If you look at the bottom bar of the cross you will see the letters "PAN" with traces of the same letters below the bar. That's how I attributed the undercoin as a colonial 8 Reales. Here's a photo of an 1817 R 960 Reis so you can see the striking difference.
