Wow amazing, you were handed a 1699 shilling in your change ?! That's something that would not happen in Oz. Yes the pictures will help, there is a thread in the beginners section on posting pics. Alternatively, seeing as you suspect you know what the coins are you could type "1699 shilling" into Google images (google.com and click on 'images') and see if you get a match. cheers Garrett.
