Transnistria is the only country in the world to have plastic coins in circulation It’s not usual plastic. They’re basically impossible to break, I’m pretty sure it’s a form of polycarbonate. And they’re not the only material coins are made of, there are metal ones too. They were made for blind, visually impaired, older people convenience - each one is a different color and shape (blind people can differentiate them with touch due to the different shapes of each denomination) and they’re shiny. Ironically enough older people hate them for some reason…
