I just "Googled" Money misprints and found a ton of listings. If you had done that before asking here, you would have had your answer, but I wouldn't have 2 points. But I do now, cause you didn't. Thanks!

Go to www.oanda.com  It is a currency conversion website that will calculate rates at different dates and using different exchange rate types (e.g.interbank etc)

The others have provided links.  If you mean the actual currency, most banks will do it for you for bills.  I don't know of many places that will convert foreign coins, though.

There is a site for collectors of currency listed below. I suggest you start there, and post your question to them, since Yahoo seems unlikely to be helpful in the answer here.
