PHILADELPHIA -- Among the mountains of losing lottery tickets piled high in a hotel conference room, someone may yet hit a jackpot.
But it won't be money that makes the winner. For members of the Global Lottery Collector's Society, the scratch-off cards themselves are worth keeping because of their quirky themes and colorful designs.
From a $3 Montana lottery ticket based on the game Uno to a series of $2 ''Star Trek'' stubs from Virginia, the game themes run the gamut from movies and TV shows to sports teams and holiday cheer.
''The whole purpose of collecting is not to get rich, or to get lucky, but to get the tickets,'' said club co-founder Bill Pasquino. ''But if I happen to hit a jackpot along the way, I'd be very happy.''
This weekend, Pasquino is joining about two dozen other club members at the group's annual ''Lotovention.'' Held this year in northeast Philadelphia, the gathering is an opportunity to meet other self-described ''lotologists,'' trade tickets and take a gander at the never-ending multitude of collectible material.
Pasquino, 64, a retired teacher from Lancaster, Pa., said that when the club started in the late 1980s, only about a dozen states had lotteries -- and none would issue more than six tickets per year.
Today, 43 states plus Washington, D.C., Puerto Rico and the U.S. Virgin Islands have lotteries, as do countries across the world.
Pennsylvania alone issues between 55 and 65 new instant games a year, according to state lottery spokeswoman Elizabeth Brassell. Recent scratch-offs include the $10 ''Stacks of Cash'' ticket -- top prize $200,000 -- and the cheaper $1 ''Dice Doubler,'' with a jackpot of merely $2,000.
While the club focuses on modern scratch-off tickets, lotteries in the U.S. date to Colonial times. Princeton University's library boasts a collection of tickets from 1761-1826, noting that lotteries were common sources of public financing because there were relatively few banks.
