I have heard of ancient coins being found in the USA before. Coins for around the time of Christ, from middle-eastern countries, and so forth, showing up at the oddest places. The truth is, people for all time, just as up to the present, have collected coins as a "curios" and for souvineers. People now who bring back a coin from other countries (like soldiers returning from WWI and WWII did) are no different from people 200 yrs. ago, or yesterday. And ancient coins have no shortage of showing up at tourist stands in the holy land and so forth, even 100 yrs. ago. Take for example the surge in popularity of Egytology in the 1920s (pyrmaid exploration, and so forth). Ancient coins then, for example, circulated about amongst collectors, and could be bought at road-side tourist markets, even back then. No doubt tourists get a few, and bring them home. So whenever these are found in the USA, they are simply a matter of someone fumble-fingering them back here.
