If it has a green seal, it's worth $12 to $15.

If just the number 1 in the upper right and left corners and it has TEN DOLLARS under the portrait it's likely a bad counterfeit bill. But just in case take it to a qualified dealer or collector to make sure it's not a unknown error.
It depends on the bill's condition and series. The series is a letter that may or may not appear next to the date 1950. The printed year is often kept the same for a particular design regardless of the actual year of issue, while the series letter is changed following the appointment of a new Treasurer (or much less often, Treasury Secretary). $50 notes for 1950 were issued in 6 series - no letter, and 1950A through 1950E. E-series notes can be worth $25 to $50 above face value if circulated, more if crisp uncirculated. The other 5 series are worth less, anywhere from face value to $25 above; again, more if crisp uncirculated. The demand for these is much less than the supply. Unless yours is an absolute gem crisp uncirculated note, you're not going to get any premium for it. If it's a gem, you might get $70-$80 if you can find an interested buyer.
You don't need to copy the serial number because it doesn't affect a bill's value. 1950A $20 notes are common among collectors and sell for face value or a couple of bucks more.
