Here is a picture of an actual bill:
Here is the one I have:
This bill has all the correct markings but on the left side below the serial number and above the diamond, the shape has been scratched off and now there is just clear plastic. The stamp with the number 2000 is there. The triangle on the right side below the serial number is the same way.
It's value is only $3.78 US, which really isn't important, we just want to know. Are Chilean bills paper or plastic?
