That was what I was thinking, too: that it arrived at some later point. Rather then providing an estimate for the date the coin was deposited, it provides only an upper bound. For example, if I go bury a 100 year old coin in my yard, it does not mean it has been there for 100 years, but it does provide a maximum possible estimate (i.e., it could not have been deposited before it was minted!).
What is needed is the dating or other items within the same stratum. Maybe they've done this (seems like a no-brainer with something so potentially important) but the article does not mention much.
