Small Currency Units ... Dollars and -- ? Pesos and -- ? ...

I'm in Israel right now and I don't even know what an agora is. Similarly, I've spent a ton of time in Thailand and Japan and had no idea there was something there even more worthless than the baht or yen. I mean... one baht is worth about 3 cents, and one yen is worth less than a penny. Is it really necessary to give change for those? :D

In Saudi Arabia the subdivision of the riyal is called a halala, and even though 1 riyal is worth 26 cents still you almost never see anybody use coins (halala) there. I think they've got a good system. Using coins is annoying, paper currency is so much more convenient, and any unit of currency worth less than a quarter dollar really isn't worth your time. Better just to round to the nearest riyal.

Israel does almost the same thing, 1 shekel is about equal to 1 riyal and, like I said, I didn't have any clue what an agora was. I think I only got them as change at the supermarket. But they still use too many coins since there is a 10 shekel coin
