Help ID And Question On Counterstamp: 1810 20r Spain?

Spanish 20 Reales.

The F.7.0 is found on coins that could be used for legal tender in the Philippines.

"The authorities eventually abandoned overstriking for the hand held die containing the King's cipher "F.7.o". This new die was more compact and could be applied with a hammer, supposedly to the obverse of insurgent coins, foreign coins and badly worn or mutilated coins. With the implementation of the new countermarks you see a greater variety of host coins, including minor coinage such as 1, 2 and 4 Reales. Smaller denominations with countermarks from this series are all rare, with the 2 Reales being the most "common" and the 1 Real being the rarest."

chowpei The counterstamp is not genuine. The addition of it to this particular coin was an attempt to create a rarity. As was said the Spanish 20R coin was not particularly well known as circulating in the Philippines. IT falls in the general category of Numismatic Forgery.

The host coin used may be genuine or it too may be a forgery. More data would be needed to make that determination.
