I've actually decided to invest in a steel stamp, with which I can punch in the word "REPLICA 2011" in about 2 1/2 by 1 inch size. I'm thinking twice on the back, one to either side of the number, should be sufficient without affecting the display characteristics.
I do realize I was being quite absolutist (thanks Tara!) and while this won't do much against the hardcore counterfeiters, it will dissuade at least a portion of people looking to make a casual buck.
Thank you for deciding to stamp these as reproductions! Like you said, it won't stop the hardcore counterfeiters, but will make it more difficult for the "small timers". The effort is much appreciated!
