http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Dstripbooks&field-keywords=standard+catalog+of+world+gold+coins Amazon I see they have gone up in price...I paid around 80 usd about 9 years ago one of the best buys I ever made.
What book you get has a lot to do with the age of the coins. Krause for example only goes back to 1600 I think it is. Whereas Friedberg goes back to ancients. Also, if you can be specific about which gold coins, I can probably offer some info myself.
Well I specialized in world gold for quite a few years, so if I can be of any help - all ya have to do is ask
