"I didn't know that," Iverson said.
"The win makes it all that much better. I've accomplished some things in this league and I've got a lot on my resume. The only thing I'm missing is a world championship. That's all I want. That's all I care about."
Iverson, who is averaging 47.3 points against the Bucks this season, reached the 40-point mark on a three-point basket with 7 minutes, 21 seconds left in the third quarter.
But the Bucks tightened the clamps on him from then on, often face-guarding him to deny him the ball. After hitting the three-pointer, he got just six shots the rest of the way and made two.
"That was a spectacular performance by Allen," Sixers coach Jim O'Brien said. "That's the quickest 40 points I think I've ever witnessed."
Iverson also added eight assists and four steals.
In reaching a season high for points, the Sixers shot 48.9 percent from the field. They took a 20-point lead, 91-71, late in the third. The Bucks never got closer than seven, but they did it several times, and the Sixers always seemed to have a response.
Twice in the fourth quarter, Kyle Korver, who shot 4 of 15 from three-point range but still managed 20 points, knocked down a three-ball to extend the Sixers advantage from 7 to 10. With the score 107-100, Iverson drained a trey - his only points of the fourth - with 3:25 left.
In his second start as a Sixer, Chris Webber shot 6 of 16 from the field, scored 15 points, pulled down five rebounds and played 25 minutes before fouling out with 2:06 to play.
"I think it's just important to get the first win with Chris," Iverson said. "That's been tough. The first game bothered him a lot because he felt he had a chance to send it into overtime. Talking about him being the second piece of the puzzle and everything, he just wanted it real bad.
