GOOD MORNING #127774; 
I will start by saying I am new to collecting paper money. I have been drawn to it recently by finding a few really cool bills in circulation. I always check my coins but didn't think twice about checking my bills until about a month ago.

I recently came across a $20 with a partial stamp on the front right near Jackson's picture. I have diligently searched the internet (Google and
ebay 
) to find something similar so that I could educate myself. unfortunately, my research efforts have not produced any solid or consistent information.

I have found numerous examples of stamps that were obviously post Bureau, but in the example on the bill I found, under magnification, it definitely looks as though this partial stamp was there prior to the printing ink being applied.

Having said all of that, I guess the main questions I have are: #1) Does this happen, meaning is there a point in the process where a stamp could have came in contact with the blank sheet of currency paper, if so, is it something that frequently occurs? and #2) If this was a stamp done prior to printing, would it be significant enough to be considered an error, if so, would it be of any value to anyone? #10067; #10067;
Basically,should I keep it, sell it or spend it?

Thank you in advance for your time and any responses. I welcome all opinions, feedback or information. I absolutely respect the opinions and knowledge of the members of this forum community. I have learned more from the people here than anywhere else when it comes to coins so I have no doubt it will be the same with paper money.
