High value foreign coins to look for?

[psi]

I was looking through some nickels today and saw a coin I didn't recognize, turned out to be an Israeli 2 new shequalim with an exchange value of more than 50 cents. I have also found a number of Cayman Islands 10 cent coins in nickel rolls, worth about 12 cents each (their dollar is fixed to the USD). What other foreign coins are people finding with an exchange value quite a bit more than the coins being searched?

I found many of them, mainly 0.02 euro in penny box and 0.05 euro in nickel, i guess we get quite a bit of french tourist here
i see many bahamas coins too (i think the exchange rate is lower for these coins)
for the rest it's very random about 1 or 2 a box and bank won't exchange currency if they are coins
Agressive Metal is buying them (http://realcent.org/viewtopic.php?f=30&t=2978) not sure if they are worth their weight in Canadian shipping cost..
