Much of the gold used in jewelry though has other materials that are valuable. Platinum is in much of this gold (as an example). If this is the case $990 an ounce for this gold might still be very low in terms of real value. The best method is to take your gold to a local appraiser and get a fair market evaluation. NEVER send your gold to a broker in the mail, unless you don't care what you get for it.
