This can be purchased for 4,482 with level 8 fame in Sandy. They are worth 830 guild points each, and you can trade in 2 of them for a max of 1359 points.
Odd, the guild NPC said that I can get up to 4,320 points on these. They're 830 a piece, so 5 can be turned in to get almost the full guild points (just shy of max points by 170.)
Instead of making yourself look stupid, maybe you might want to take into consideration a couple of things:
1) This website doesn't always have the correct information. 2) When an item is first discovered, either by auto-collection, or by players confirming its existence, it's not always apparent how the item is acquired. 3) There's no year tacked onto the posts, so maybe... just maybe... the post was made way before the info about which mobs dropped it was added to this entry.
