The "peseta" denomination was first used for Spanish coins in 1869, and out-of-focus as they are, the pictures do show enough of the design to say it is not a Spanish 5 peseta coin of any age. Peru, the Phillipines and Puerto Rico all listed by Krause as having used that denomination, but not in 1814. With better quality photos it may be possible to ID the piece.
The coin is real I had it valued 2 years ago but have since moved to spain.. It is maked *EN*BARCELONA*1814* is silver will post better pictures asap.
There's the problem. Krause lists it as "local" coinage, separately from the main Spanish listings. Barcelona, a maratime province in northeastern Spain with a capital city of the same name, was under the rule of Joseph (Jose) Napolean from 1808-1814. Its monetary system had 4 quatros = 1 sueldo, and 6 sueldos = 1 peseta while the Spanish government was still on the reales/escuedos system. The 5 peseta silver coin is KM#69, weight, fineness of silver and mintage not specified. Based on the values in the 3rd Ed. 19th Century Krause, the 1814 is the rarest (probably because Napolean was thrown out that year, and King Ferdinand VII regained control). It was the largest silver coin of Barcelona, although there was a 20 peseta gold coin. The 1814 is valued by Krause at $1,000 G/$2,100 VG/$2,800 F/$3,500 VF, with higher grades not mentioned. For earlier years the values are $100-300 G/$225-600 VG/$325-900 F/$450-1,250 VF. Please do! From the ones now available it is just about impossible to form an opinion on grade, genuineness, or possible cleaning; all important factors in estimating a value.
