When the Commonwealth of Massachusetts started making Red Sox and Patriots license plates, they sold like hotcakes. The state has a policy with new license plates, where they only start making them when 1,500 are ordered.

For the Patriots and Red Sox plates came out, they reached 1,500 almost immediately. The Bruins took a little longer, but still only 5 months to reach the magic number.

The Celtics, on the other hand, are clearly #4 on the totem pole. Celtics license plates were first offered in 2006, and last month, the 1500th plate was finally ordered, allowing the state to start making them. Congrats, Celtics fans. You're #4!
