Not holding my breath, but: The Japanese solution works very very well. the 100 yen coin (their system's $1 equivalent) is smaller than a US quarter and much lighter than a british pound coin. The 500 yen coin is about as big as a Susan B. Dollar coin, yet is still quite light. I often have as much as 2000 yen in coins in my pocket at a time, and it doesn't feel particularly heavy. Paying a transaction under 1000 yen is generally quick and pleasant. Contrast with US $1 dollar bills, that are for some reason almost always falling apart, crumpled rags, and with the Quarter being the largest coin in common circulation, paying for something under $10 inevitably means fishing out a mix of disintegrating bills and small change.
