Authenticity Request; Philippino Countermark On Bolivian 8R

The Philippine Counterstamped coin on an 1831 Boliviana coin 8 Soles (Soles is slightly smaller in diameter than 8 reales but they are equaled and circulated as 8 reales) is a Very nice 5-4-dot pearl formation and indeed an authentic one. It's becoming scarce with that condition nowadays. 5-4-dot pearl formation means there are five dots on both sides followed by four dots and a dot on the center. The base of the crown of the CS is the normal type 1. That 5-4-dot formation means it was the first type of countermark bearing F.7.o 1832 Thus the host coin 1831 was made into CS for Philippine circulation during 1832, Philippines' 1st year of counterstamping (smaller marks) South American coin after Manila counterstamp machines broke off.
That coin could easily fetch over US$300 as of todate Feb 2011 and by just a mere look of the obverse, no doubt that the coin is definitely genuine.

Now for the English one...
The coin is good, the countermark OK I think. I am concerned about the lack of detail in the portrait on the countermark - at the time of issue there were lots of contemporary fake countermarks, which eventually caused the BOE to recall them and overstrike them as 1804 BOE dollars. It is extremely difficult to tell the fake from real countermarks.
The fuzzyness on the countermark below is caused by my scanner, but you get the idea. FWIW I presume mine is genuine too!
