Greetings I recently acquired a Spanish silver pistareen ( 2 Reals ) dated 1718M but it weighs only 5 grams instead of 6.7g ( KM 307 ).I don't know whether it's a variety or an error orwhatsoever. However, the main important point is the mystery behindexchanging a piece coin of 8 Reals for 5 pistareens ( 5 x 2Reals = 10)instead of 4 pistareens ( 4 x 2 = 8 Reals ) by that time in America , namely the United States Which was under British rule then .Maybe that was to equalthe value and weight of silver. ( scan attached ) ArtCoinerCould any member give me an answer .Please
It appears to have been holed and plugged twice which might account for the low weight. The exchange difference was because of a weight difference between coins made in the spanish colonies compared to those made to the same weight but they were 931 fine at the time compared to the home country's 903 fineness. This meant that the Spanish coins contained less silver. So while the Colony coins were valued at the equivalent of 25 cents or a quarter dollar, the Spanish 2 real was valued at 20 cents or a fifth of a dollar.
