For each Anniversary Crate, you have a 10 percent chance to get a rare item, 30 percent chance for uncommon item, and 60 percent chance for common item. The items you can get from an Anniversary Crate are the following:
Common
Cuban Underground (29 Attack 40 Defense)
2 Candles (40 Attack 28 Defense)
Iron Curtain (30 Attack 39 Defense)
Uncommon
Big Apple (46 Attack 33 Defense)
Party Popper (32 Attack 46 Defense)
Party Favor (45 Attack 34 Defense)
Rare
Terrible Twos (64 Attack 40 Defense)
Chop Suey Chaser (37 Attack 65 Defense)
The stats from the Anniversary Crate items are decent enough. If you got extra Reward Points, you should buy a crate or three. These items are good additions to your Mafia Wars collection. AT least you have proof that you were part of the game’s second year anniversary celebration.
