My mom came to me with billions of random batches of Korean Wons. FYI: Won is the Korean currency like Dollar is to the U.S.
We counted them — I have over 80,000 Wons and can be roughly converted to 80 Dollars more or less.
The trick I learned when I visited Korea a few years ago was to take 1,000 Won and erase the last zero. Then I would use the comma as a period. So 1,000 Won became 1.00 Dollar roughly.
Hey, it helps … me at least! Haha.
