History: Items Out of Use

General
The first source of information on new items in FFXI is generally coming from people who decipher the .dat files of FFXI and get the item informations from there. But not all items listed there can be obtained in the game. Of some items players even thought they knew how to obtain the item, but it was not working in reality. Some or all of these items have by now been removed from the .dat files, but many websites for FFXI information still list these.

Goldsmithing 102 High Quality Rings
These are the best example for the case listed under General. These Rings where supposed to be the high quality results of a Goldsmithing 102 synthesis. But many goldsmiths reported by now that they have seen a high quality animation on their synthesis attempt, but did not get any other result than the normal one. During one of the monthly updates the information on these Rings have been removed from the .dat files, finally confirming that these Rings never existed and will never exist. The Rings in question are:
 * Neptune's Ring supposed HQ of Aqua Ring
 * Auster's Ring supposed HQ of Breeze Ring
 * Pluto's Ring supposed HQ of Dark Ring
 * Vulcan's Ring supposed HQ of Flame Ring
 * Apollo's Ring supposed HQ of Light Ring
 * Aquilo's Ring supposed HQ of Snow Ring
 * Terra's Ring supposed HQ of Soil Ring
 * Jupiter's Ring supposed HQ of Thunder Ring
