In Chile they have 1 peso pieces so small and light you can blow them from your hand like fairy dust. The only stores that use them are big chains that operate on enormous economies of scale, e.g. Hiper Lider. When backpacking there (on very little $) a homeless person asked me for some change. I dug into my pocket and offered him some change and he just lauuuughed at me. Interestingly, $1 USD = ~800 Chilean pesos in 2020, but was over 2000 Chilean pesos in 2006.
