Information on 100 Dollar Bill and Replica Coin

I found this 100 dollar bill on the ground and at first I got excited thinking I found a Hundred Bucks but when took a closer look at it I found that it was a Movie Prop with Chinese Letters on it. From what research I have done that is where the confusion is. I don't know if it's really a movie prop and or teaching tool for Asian's to learn how to count American Currency. I've seen a few examples of this kind of currency online. I just don't know if it is or isn't you know. 

For the Replica Coin, I bought it for a buck ($1) and I was curious cause it say's its the first silver dollar of america. Does anyone have any info. about this coin? 

Thanks again.

This is the coin from which it was copied:  N#18852

The banknote is a real movie prop note overprinted with Chinese to train tellers like this note: N#259193  I saw another post where the text on the back was translated as, “Practice bill. Specialty made for practice. Do not circulate.”
