We have the loonie and the toonie (1,2$), and they make your pocket heavy. Boom & Gary of the Vermilon River, Canada.
When we were younger, pocket change sometimes saved the day just before the day we got the paycheck! Now it's just heavy metal.
I just a changed a pile at the bank. I got €23.23c / schrott, schrapnel, munzen, the Germans have a word for it.
