For example, nalaberong buys Israeli shekels and other foreign coins with higher exchange value than their price, even though he/she doesn't live in those countries. For free, if someone were to find a lot of these, they could make a few dollars in exchange value.
Yes but this is only 50c I wouldn't put any effort to gaining 50c because there are so many easier ways to do so but I'm not telling others not to do it I'm just saying that it's not worth it
There are companies who buy currency. It used to be that you could really only count on exchanging banknotes but I found a place online which accepts coins too. Of course they don't pay face value but I've sold a lot of junk coins to them in a $5.95 flat rate box for well over $100 on several occassions now.
Since then I've been making it a habit to pick up Marks, Pounds, Canadian Dollars and Swiss Francs and add any lower denominations I get when buying bulk lots. Whenever my box of junk currency gets full I mail it off and get a nice check within a week.
Non illegitimis carborundum est. Excellent advice for all coins.
