The US Mint has issued new regulations that authorize fines of up to $10,000 for melting down US coins. This is in reaction to pennies and nickles being currently worth more for their metal content than their face value.
That is pretty understandable, but there is a rather strange regulation thrown in as well. You can no longer leave the country with more than $5 in change. I don't know what that is about or why the amount was set at five dollars.
