Tax Or Duty

Quote:
Based on US has no taxes or duties on bringing coins and no limit on the amount of money that can be brought in or taken out of the country as long less than $10,000.- or I declared, I am OK. That bring me to next question, how you see it the coins as face value (few dollars) or Gold or Silver value (few hundred dollars, Numismatic value (few thousand dollars)? As face value, I am way lower than $10,000.-, even if I bring hundred of coins. Should I clarify with the Custom and Duty Office to make sure?
Libertad, what about ASE, is that count as $1.- too?
