Outside of Zim, I believe the worst inflation occurred in Yugoslavia in 1992; so, not that long ago.
Of course, by the time you are wiping out three zeroes, everything is pretty much a rounding error
Hyperinflation in Yugoslavia:
“Between October 1, 1993 and January 24, 1995 prices increased by 5 quadrillion percent. That’s a 5 with 15 zeroes after it.”
I think the highest on record is Hungary after WW II hitting a peak monthly rate of 41.9 quadrillion percent. In the course of a year the Hungarian Pengo went from 1,350 pengo = $1 US to 4.6 X 10^29 (460,000,000,000,000,000,000,000,000,000) pengo = $ 1 US. The largest denomination issued was 10^21 pengo note (10,000,000,000,000,000,000,000). The highest monthly rate in Yugoslavia was 313 million percent. Zimbabwe easily beat that with a peak rate of almost 80 billion percent.
