Looks to be pretty rare since there are none in my server's Bazaar and Magelo has no info to speak of about this item.
I'm getting intrigued by "Collectibles" and thinking of making a post about them with a complete list along with the mobs and locations they can be found. Magelo has plenty of info on collectibles that drop from mobs but nothing much on ground spawns since I guess their item collector does not gather info about where a ground spawn was acquired. This would be very helpful info.
Some very rare ground spawns, I suspect a player has discovered the location and is pharming them as soon as they pop because on FV there are collectibles of this sort being sold only by one player, he has a quantity and he usually charges a LOT per unit. By "one player" I don't mean anyone specific, just that someone found the spawn spot and is trying to monopolize it for fun and profit. That's a guess on my part but it seems plausible when a collectible priced at 100k or more is only sold by one seller, and he has a quantity.
Knowledge is the key! If everyone has the knowledge nobody can hog the pops!
Well, to avoid re-inventing the wheel (!) Fanra has a nice list of ALL collectibles right
