Where are these "chop marks" from?

Hello I'm Jack,

Yesterday, I noticed these strange stamps on two $5 bills I had and after like an hour searching google, I found out they were called chop marks.

According to Dictionary.com, chop marks are "a notch or other mark made in a coin to indicate verification of its authenticity, esp. by a banker or merchant in the Far East during the 18th or 19th centuries." Is this correct?

Only thing I'd like to know now is which far eastern country these are from. I couldn't find anything on google.

 

 

These first two pictures are on the same bill.

1-2)Year-1999. Second image says "cc3".

 

 

 

 

3)Year-2001

Hi Jack,

 

I suspect those are stamps used to verify the authenticity of a bill. If I'm right, the stamp will be one color if it's a fake bill, another color if it's legitimate.

 

Others will surely chime in if I'm wrong.

I think thedeadpoint is correct on this.
