So you've just described counterfeiting. What am I missing?

  Yes, I've described counterfeiting. The question is whether or not it would work. Generally, physical items undergo somewhat predictable physical changes as they age, allowing experts to determine the approximate age of an item. To counterfeit with an acceptable level of risk, we need our counterfeit to appear to be the right age. I'm asking if using authentic period paper, ink, and staples would be sufficient, or are there aging effects that depend on how long the ink has actually been applied to the paper?
