Going for around 700k on Siren if I am not mistaken. I remember seeing that about 5 had sold so far. Seems that auto-collection got this one right. I cant wait for the price to drop...if it ever does.
Somepage says it drops from the Eye of the Tiger BCNM50 3-person fight in Horlais Peak after trading a Comet Orb.
It is listed in the Jeuno AH on Bismarck but none have been sold so there is no price history. However, because it's a BCNM drop expect it to be expensive.
If it's "Submitted by Auto-Collection" then it's likely one of those items hidden in the code of FFXI that hasn't been (or won't be) implemented. I have definitely never seen this at the AH nor on anyone. And you know that if it were easily available every BLM 50-65 would be wearing one.....
