As I replied to you elsewhere just now, a numismatist (coin specialist) is the person to contact for rates on coins.

If, however, it is a coin that is still in use (as Euros certainly are),you can check at http://www.oanda.com/convert/classic?user=onlineconversionlang=en which gives you the latest rates for masses of different currencies.

Right now, Monday, March 2, 2009, they say

1 Euro = 1.26723 US Dollar

(Note, however, that most banks don't take coins in exchange, only bills.)

With a Euro coins (not bills) you can tell the country where it was minted by looking at the obverse (back) side: each member-country has its own logo or pattern, with the name of the country.
