My change jar - actually a plastic box. 

I emptied out my change jar this morning, and took it down to the bank.

The bank has an automatic counting machine. After the noise stopped, my bank account was $37 better off.

While $37 doesn't seem much, getting it was completely painless.

I looked closer at the woman's finger.

"Excuse me," I said, "but what's that sticky tape around your finger for?"

Because underneath the clear tape was a large diamond. And she was wearing it like a ring.

Except there was no circle of gold holding the diamond to her finger.

The auditorium was packed full. An air of expectation made the crowd buzz.

Nearly 2,000 people were here to listen to one of our country's top property millionaires reveal his secrets.
