Gally really isn't that rare. I've had 7 or 8 of them across all the activities. I even bought one from Xur when he sold it 10 days after release. I don't understand how anyone can call it rare when everybody had the chance to buy it for 17 Strange Coins in week 2. Everybody, and I mean everybody I play with has at least one, and I play with a lot of people.
