This bonus hunt has been solved and five (5) TREASUREFIX searchers have been rewarded with $100 cash each.

In the “nick” of time implied to look for some possible nicknames within the image. One is the note itself: “The Grand Watermelon” is regarded as the “Holy Grail of American currency” and is placed at #1 in Q. David Bowers and David Sundman’s 100 Greatest American Currency Notes. The other, pictured within the note, is General George Meade: nicknamed “Old Snapping Turtle” on account of his notoriously short temper.

The next step would perhaps only be intuitive at this point if you were already thinking about various forms of “coding” on U.S. currency, including the Letter/Number combinations of the Federal Reserve Banks (whose job it is to issue all U.S. currency). By adding the letter values of the two nicknames to one another (A=1), you would reach a value of 426, which is the equivalent of J (sixteen rotations through the alphabet with a remainder of 10=J). J (or 10) is the code for the Federal Reserve Bank of Kansas City (that, or simply Kansas City was an accepted response for this puzzle).

The hint “It's not in D.C.” had threefold meaning: (1) the answer was not Washington D.C. or anything located there; (2) there is no Federal Reserve Bank in Washington D.C. (though the Federal Reserve’s headquarters is located there); and (3) there is famously no “J Street” in Washington D.C., as city designer Pierre Charles L’Enfant either disliked the similarity (and possible confusion) of the letters I and J as styled during that time, or had serious beef with John Jay (depending on which story you choose to believe).
