This was working till 2 digits inflation, and before widespread digital payments. Now it's just inconvenience to carry bunch of worthless papers, that takes forever to count, not to mention the cost of manipulation for businesses and state. To get 1 mio usd worth of peso to the bank is now logistic project, that cost a lot more than it would, if you would have higher notes.
Last time my son found 2 peso coin, and I almost cried. 10 years ago it was common payment option, now is less than worthless. Businesses just put prices in round 00 now, and will be doing 000 if needed. Have no impact on inflation itself.
