50 Soles de Oro

Peru's sol had been inflating steadily through the late 1970s, but the early 1980s brought a sharper deterioration that quickly rendered 50-sol coins nearly worthless in daily transactions. The government's response was to keep issuing them while simultaneously planning a full currency replacement — the inti, introduced in 1985, arrived at a conversion rate of 1,000 soles to 1 inti, a ratio that says everything about what happened to purchasing power during this coin's production window.
