An annoying amount of Myanmar Kyat considering I have never been to Myanmar. Also have a load of Kuwaiti Dinars, lots of Brunei Dollars and smaller amounts of about 30 others.

Currently just USD, THB, and JPY in my wallet. The baht because I never got rid of it after my one and only trip to Thailand and the yen because I travel to NRT frequently and it's helpful to have it on me.

The collection at home is an entirely different story...

Have a lot of coins from far more countries' currencies sitting around in jars in some rooms of mine in Asia, Europe and North America; however, when it comes to coins and cabin baggage, I only seem to carry coins for the following: USD, GBP, CAD, NOK, SEK, DKK, EUR and CHF.

Frankly, I have a yen to go baht and make my mark...

I avoid having excess foreign currency like the plague, and normally only keep serious amounts of cash in currencies I use often, which are CAD, USD and GBP (although only to feed my online gambling). Of course, I have those pesky little small notes and coins which I have leftover from currency exchange, etc.

In my actual wallet:
CAD (Canadian Dollar)
USD (US Dollar)
CAD Credit/Debit cards
USD Credit/Debit cards
HKD Credit/Debit cards

Money I have lying around:

In a huge jar at home, I have probably 40 currencies. Mostly coins with some small banknotes in there. Most of the pre-Euro European ones, a half dozen or so Asian ones, some Middle East, and a few Caribbean/Central American.

I generally try to keep 20-40 each of EUR, CAD, and USD onhand when I travel. Or at least two of the three. Yeah, I'm a credit card guy like most FT'ers, but enough cash to buy a subway/train ticket or a meal prior to finding my first ATM in a given country can be handy.

70 CHF (Swiss)
10 Euro
5 AUD (Australia)
5000 Colones (Costa Rica)
15000 Pesos (Mexico)
90 RMB (China/Yuan)
Handfull of Italian Lire Coins (now worth collection value only)


I wish I could get rid of the Yuan, but I was told there is no way to exchange it for USD back here in US, though only worth about $12 I suppose.

You can convert CNY quite easily in the US, it's just that the fees for such a small amount would make it completely not worth it.

The Panamanian currency is called the Balboa. It operates in parallel with the USD, but Panama does mint its own coins.
