A very odd rendering. Not much more than a cross to go on, but the other side shows the pillar and waves design that was used in the Peruvian mints of Lima and Potosi from mid-1600's on up through the late 1700's. You can read part of the word "Peru" on the pillar side in the upper left corner. Not much else to go on for narrowing down the year. The striped pillars are one of the really odd looking features. Hope this helps. Oh yeah, the denomination being copied is probably 8 reales.
