getting the right value for my gold necklace and coin in Toronto?

I own a thick gold neclase it is 14k. Attached to the chain, is a 500 Lira gold coin commemerating the 25th anniversarry of the state of Israel. The total weight is 69 grams.
How much is this worth? Where can I go to find it's value, and where is the best place to sell it in Toronto Ontario? Would this be a collectors item?
Thanks Silverpet,
I would at least like to know how to get a fair price for the gold content in both the neclase and the coin. The total weight is 69 grams like i said above, the neclase is 14k, but the coin itself is a higher percent gold than that- not sure what. I really would like to sell this- where can i go to get an honest estimation as to how much i could sell this for?

More to sentimental than collector value, I'm afraid. I'm not an antique collector or evaluator, but I'm a coin collector and I can assure you that once a coin has been mounted to a pendant or in jewellery, it will lose its numismatic value. Numismatists and hobbyists consider jewellery coins as damaged coins, unless in cases of extreme coin rarity then it could still fetch high premiums which the Israeli gold 500 lirot is not. But all is not lost... if you decide to remove the coin for sale, then you will still get the gold content value. Sorry to disappoint you, but most damaged coins are only worth bullion if struck in precious metals. Also, many Israeli gold and silver coins have been melted in the late 1970s when the price of gold and silver passed $800 and $50 per ounce respectively... the demand for the coins just wasn't there. You could bring your pendant coin to a Toronto coin dealer, and I'm sure he/she will say the same thing.

Update:
Just read ur additonal comments. Well, the 500 lirot 1975 coin commemorating the 25 Years State of Israel Bonds weighs 20 grams, has a gold fineness of 0.900, and contains 0.5787 ounce of pure gold(in uncirculated condition). So here's what I could figure:
The gold coin, 0.5787oz gold = Approximately US$385.
The necklace, 14k gold(assuming it's 14k alloy, not plated), 49 grams = Approximately US$614.
Total is about $999, but of course, coin dealers or goldsmiths pay less. Good luck.
