If you play Mafia Wars, you know about the collections that can be vaulted in the game. You also know that the lotto collection seems nearly impossible to vault due to its high rarity and how it never seems to be found. In order to vault this collection, the pieces must be obtained in the Daily Chance lottery. This is a mini-game in which Zynga gives all players a free ticket every 24 hours and once a week, the winning numbers are drawn.

By matching three of the five numbers on each lotto ticket, a piece of the collection can be won. However, in order to complete this on your own, you would need to win eight pieces. The odds to win in Mafia Wars lottery is less than that of actual lottery. This prompts people to set up trades.

Knowing full well they cannot do it on their own, players have decided they would rather get a large quantity of other items, loot that is more common but still fairly valuable. For example, the Zoloto Sports car and Ubijca Assault Rifle are pretty good items, and those with lottery collection pieces may be willing to trade their piece for anywhere between 50 to 100 pieces of your loot. That is a common price as well, considering the rarity.

What this ever so rare and highly demanded lottery collection actually does for the player in question is a potentially useful bonus for some players, though it may not be for everyone. When the collection is vaulted, players are rewarded with an additional 10% chance to obtain loot from jobs. Without the bonus, the current drop rate is about 20-30%, which bumps up the chances to 30-40%. As such, loot from jobs drop at a much higher rate.
