Well, here's another answer for you.....
Internet is absolutely amazing..... I thought I had to drive across town and find a friend's auntie and have tea to find the answer for you. I found someone I know in China who could tell me the answer in english so that was easier. And I didn't even have to leave the house!
so here is the response. Hope it helps!
Good morning (Sunday) from shanghai...
(1) To start with the coin...
as you can see, there are 4 Chinese characters, as represented by 4 directions.
in this case, we read it in a direction from north to south and then from east to west
So, it is read as Fu ( Fortune ) --> Shou (Longevity) --> Hang (Health) --> ning (quietness)
(2) About the round thing on top of the coin, I am not too sure, but I can find it by asking others.
(3) About the 5 Chinese characters on the far right of the page... and your are right it has to do with the heart.
it is read from top to bottom vertically. It sounds like " ting xiang ni de xin"
Literally, it means "listening towards to your heart", or simply it means "listen to your heart"
let me know if you need additonal help.
