The not so mighty US dollar - a few 'Ben Franklins', what do you use?

Yesterday I changed some South African Rand (our local currency) for US$. I leave for a trip to Israel this week. The SA Rand is not a strong currency (we pay about R8 for US$1), but there is little doubt that the US$ is weakening. Regardless, it hurts to pay R8 for $1! When I last visited Israel it cost $1 to use a public toilet, that's R8 to 'spend a penny'! Yikes!

Let's not talk about Pounds, when I was in the UK last year it was R16 to £1!

One day I'll post pictures of my 'money collection'. So far I have currency from:

- Israel
- Turkey
- Morocco
- Algeria
- Tunisia
- Egypt
- Kenya
- Zambia
- Mozambique
- South Africa (of course)
- Zimbabwe (I have a $1 note! How rare is that!?)
- Italy
- Spain (before the Euro)
- Australia
- Russia
- South Korea
- Malaysia
- Singapore
- United Arab Emirates
- USA
- Argentina
- Greece

I'd be interested to know what currency you use (if you're outside of SA)?
