Would currency from another dimension be considered counterfeit?
<p>This is, of course, entirely hypothetical. We are assuming that the currency is otherwise identical to the currency of the country in question. While I am open to the legal implications for the country of any available answerer, I would like to know what the answer would be for the United States, Argentina, The United Kingdom, Mexico, Canada, and Australia in particular. (Sorted in order of most curious for the answer to least curious.)</p>

<p>Yes,
I would count it as counterfeit as the serial codes will already exist and you are bringing the other dimension $ to this one so they would be the "copy"</p>
