>Mexico has a half peso coin, worth about 2 cents.
and a peso was like a dollar.
I recall my aunt feeling guilty about what she was paying down there when it dropped to about eight to a dollar.
And then they lopped three zeroes off to get the new peso.
I *think* this is half of those one-thousands of the prior peso . . .
After extreme inflation, small matters of rounding aren't even on the radar for what's important.
[Let alone the 27 or so zeroes lopped off in Germany {where, near the end, workers were reportedly paid twice a day, with their wives bringing wheelbarrows to collect, and rushing to spend it before it fell further! (which may be an urban legend; I've never been able to confirm it, but it's not inconsistent with the daily inflation)}. Or Yugoslavia, which lopped off 30 digits . . . ]
