Making millions with just 3 100-won coins

It took 13 years but the three 100-won (9-cent) coins turned into 1.39 million valued at 139 million won ($128,000).
In terms of math, this would be the multiplication of one coin by 97, each reaching 463,216 over a period of 4,757 days.
This is the story behind the three 100-won coins.
It all happened when a person’s mother was arrested for stealing beef from a supermarket.
And then what happened the man started a group for helping neighbors with 100 won a day. This led to an increase in the number of donor and an account was made to the amount of 470,000 won ($4,300).
In 1999, a district office established a fund named the “100-won Fund.”
It took a little time but 13 years later today, it has grown to a sizable fund that is providing charity to various parts of the community.
