Mercury

I was with my friends and i opened my mouth to say something, and someone threw a dime in my face. i am scared i might have swallowed it. what happens if you swallow a dime? does it get stuchk in the liver or in the stomach? is it poisonous? does it have mercury in it? im scared. help.

2 to 3 days later you have a sh it worth $.10 it may have gone down in value considering its location.
