A few weeks ago, Bungie responded to a tweet asking about a strange coin found in the tower. Bungie stated if you find them all to send a picture and the first person to find them gets an award. Bungie's Update: http://www.bungie.net/7_Bungie-Weekly-Update---09262014/en/News/News?aid=12192 I do not know who found them first, or if they were rewarded but I do know 7 (assumed by the community to be only 7) have been found and I'll show you where to find them :) 1. Tower Plaza: From spawn, 4 small pillars are in front of you with red flags. When facing away from the traveler, the first coins is in the bushes on the third pillar from the left. 2. Tower Plaza: From Spawn, head to the large tree next to the Gunsmith. The coin is located on one of the branches. 3. Tower Plaza: From spawn, head to the upper level above the entrance to North Tower and to the left of the Special Orders Vendor. Up stairs there is a ghost, on the crates to the left of that location is a coin on the edge of a crate. 4. Hall of Guardians: The Hall of Guardians is where the Hunter, Titan and Warlock Vanguards are. Run past them to the Robot at a desk on the right hand side. Look out the very corner of the window to see the coin on a ledge. Best done by crouching. 5. Tower North: Once you've entered Tower North, run forward past the Map Robot the wall straight ahead. The will be a desk with large cannisters on it and a tall Pillar next to that. Jump on the desk, then jump in the air and the coin is on the pillar. 6. Tower North: Once you've entered Tower North, go to see the Speaker. A coin sits on the desk right in front of him. 7. Tower Hanger: Once you've entered the Tower hanger, go down the stairs below the FWC and to the right of Dead Orbit. This takes you to what I assume is a BAR. On the table on the left hand side is a coin. The table is surrounded by 3 chairs with no NPC's sitting there.
