If you have ever done that or similar in the past you would have a history of Google banning that adsense account at some point.
You may get a couple of months of checks, although that is not the norm, but you will surely lose that account and any money in it when it does get banned.
As to how much you would get for an American to click that depends on the ad cost to the advertiser and which Americans you are talking about.
There is North America, Central America and South America and they all have multiple countries.
