How much is a garden state parkway token worth?

Now? Nothing. They were officially phased out in 2008, and they are no longer valid. However, for people that had them laying around after they stopped being sold in 2001, using them saved quite a bit of money. They originally sold for $10 for a roll of 40, just like quarters. Then it was $10 for 30 after the toll went up to 35 cents (you got a 2c discount that way). But for those who bought a bunch and sat on them for a while, they made a very wise investment, because they continued to be accepted even in 50 cent and $1.00 toll lanes.
