$24. The star means that the mint orrigionally messed up on the bill and replaced it with a new bill.
At least one dollar
As you have seen in many other postings, a bill's serial number almost never has anything to do with its value.
The fact that it has a T in the serial number neither identifies the bill nor affects its value. 1957 is the most common date for $1 silver certificates. In anything but top-quality condition it's worth at most $2, generally closer to $1.50.
1957 $1 silver certificates aren't rare. In general they're only worth about $1.50 in average condition. The "P" at the start of the serial number doesn't help to ID the bill. Serial numbers are counters and a security feature but rarely affect a bill's value. Some collectors will pay extra for numbers with a special pattern, e.g. 12345678, or low numbers such as 00000015.

Oh, dude, you're asking me to pinpoint the value of a specific dollar bill from 1957 based on its serial number? Like, I'm good, but I'm not a psychic, man. You might want to take that rare bill to a currency expert or something if you're looking for an exact value.
The value of a 1957 silver certificate dollar bill with a star in front of the serial number depends on its condition. In circulated condition, it may be worth slightly above face value to collectors. In uncirculated condition, it could be worth around $10-20 to collectors. The specific serial number does not significantly impact the value in this case.
About $1.25. These are quite common among collectors. As you've seen from other posts, a bill's serial number is unimportant to determining its value.
With that serial number, you could get $100 for it.
A bill's serial number doesn't usually affect its value or help ID it. What matters is the date, seal color, and what letter if any is right next to the date. In your case, circulated 1957 silver certificates are so common among collectors that they're usually only worth $1.50 to $2.00 at retail. A dealer will pay $1.00 to $1.50 depending on condition.
Depends on year and how low the serial number is.
More and different information is needed. Please post a new question with the bill's denomination and the letter, if any, after the date. The serial number is not a factor in its value so that doesn't have to be repeated.

This is a common date. They are worth $1.25-$1.50 in circulated condition and $3.00 or more in uncirculated condition. Note: The serial number on a bill rarely changes the value of a bill so it is not needed to figure out the value.
