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.
To clear things up, the bill wasn't printed in Philadelphia. That's the Federal Reserve District that distributed the bill, but it was printed in Washington. Please see the question "What is the value of a 1950 US 100 dollar bill?" for more information.
The green seal indicates that your bill is a Federal Reserve Note. Please see the question "What is the value of a 1950 C US 10 dollar federal reserve note?" for more information.
1950-E is the most valuable $20 bill in the 1950 series. As of 09/2012 values are in the range $50 to $65 for a bill in circulated condition. An uncirculated one can bring $90 or more.
Please don't assume that because a bill is old it must be a silver certificate. The last US $20 silver certificates were printed in 1891. As you can see by the banner across the top of the bill and the green seal, your bill is a Federal Reserve Note. There's more information at the question "What is the value of a 1950 US 20 dollar bill?"
Please check your bill again. "E" is the highest series letter for 1950 $20 bills. You're probably looking at the Federal Reserve District letter instead; the series letter (if any) is next to the date. When you've identified the series letter, check the question "What is the value of a 1950 [letter] US 20 dollar bill?" for more information.
