What is this thing?

[RemOfShadows]

Basically I just want to know what is this and what's the deal with it.

I know it's an ancient Chinese coin, and I've seen people carrying these around, although I have no clue what it represents...
In case you're wondering where I got it, I found it while cleaning up the store, in the little bag and everything, since then I's just been lying around my bag...

You have a Cash.

They were used as currency in China (un-officially) until the mid 1900's.

I think they're like put on necklaces now-a-days for good luck.

Figured as much, I wonder if the piece of paper has any meaning too...

White on the inside? Colored on both sides? Words or anything?

Colored on both sides, with some Chinese letters on it, although now that i actually took it out, it's folded to form a little pocket of sorts, so I'm guessing the coin was in there at 1st, or is maybe meant to be given as a gift with the little paper pocket.

those sort of coins are sometimes used in charms of Luck in finances or luck in general. Japan has a thing with those too, i still have my little trinket from an exchange student i received in 4th grade. Kinda looks like this:

the knotwork on my charm was so old and tattered from being a keychain that I had to look up how to make a new one.
