Odd $5 Bill - Too Much Ink?

I bought a scanner yesterday and amazingly enough the same day I received this bill in change. There are several odd things about this wash effect.

---Front of Note---



1) Notice the white spaces on the right side. They perfectly line up with the facial features of the watermark.

2) If you shine a light to expose the watermark you'll see that it is much thicker than what is on a normal bill. In fact, you can't even see any detail of a left eye. It's just a big blob.



---Back of Note---



1) It almost looks like a pattern, especially on the left where you can see the dotted line.

2) Near this dotted line you'll see what looks like an '0' followed by other characters. That is in fact the B and the rest of the serial numbers.

3) You'll also see near this area that it looks like there's a face to the left of the Lincoln Memorial. (A security feature?) There's also a slight one on the right side but you can't see it in the scan.

4) Also, look at the way the wash avoids where the security tag is.
