just dollars and dimes Making change would require an average of 4.5 dimes, with a maximum of 9 that happens 10% of the time. Currently 9 coins are required only for 99 and 94 cents. (That's without half dollars, if you use them then it's only 8). If you have dimes and half dollars, it's an average of 2.5 and a max of 5. Also, US dimes are small and lightweight I find them to be too small. I like the simplicity of removing a decimal place, but I'd prefer penny-sized dimes and quarter-sized half dollars.
