So you buy for 49.9mil on auction safe at tram brit then turn to stratics to sell? lol
Maybe he killed 151 Yamandons or Serrado, or maybe some1 gave it away, or bought, or who cares how the item was obtained? The point is that he saw value he recognized it and obtained it, and kept it.
The prices posted are very fair, and he is making it available to you to purchase it if you want it.
It does look like an awesome shield, likely worth much more.
