It is quite possible. Counterfeit detection pens are generally inaccurate at best and can mark some older genuine bills as counterfeit and counterfeit bills as genuine, and as such should only be used if there is a lot of question about the bill's authenticity. Keep in mind that 1950 US currency in high grades can be valuable as a collectors item and a counterfeit detection pen may very well ruin a lot of the value.
Verifying if a 1950 one hundred dollar is counterfeit can be done in a number of ways. Initially check for a thread pattern in the paper. US currency has paper with a rag content including visible threads. then check for a watermark. A watermark cannot be xeroxed properly. Finally, the disclosure pen found at retail stores can check the chemical content of the paper to verify authenticity.
No US paper money has silver IN it; all bills are printed on special paper that's mostly cotton and linen. If you're asking if the bills were silver certificates - i.e. could be traded for silver at that time - the answer is again no. All 1950 $10 bills were issued as familiar green-seal Federal Reserve Notes.
The composition of the bill was basically the same then as it is now, though it lacks modern security features. If tested with a pen, it should turn whatever color it's supposed to for a genuine note.
First class US stamps in the US were 3 cents each.
There was no US silver dollar minted in 1950. If you mean a half dollar, it would be worth at least its value in silver which as of writing is about $7.70 but it would be worth more in better condition. As with all old coins, cleaning harms the value.

The pens should work, but differences in the paper over time may give a false indication that the bill is counterfeit. Bank employees are trained to identify these older bills.

Counterfeit pens are unreliable and do not work on currency printed before 1959.
The lack of "In God We Trust" on a 1950 twenty dollar bill is not indicative of a printing error or counterfeit. The motto was added to U.S. currency starting in the mid-1950s, so bills printed before that time do not contain it. To determine if a bill is a counterfeit, look for watermarks, security threads, color-shifting ink, and other security features typical of genuine currency.
No, a real 1950 twenty dollar bill should not be marked as fake by a counterfeit pen since the technology used in the pen is designed to detect specific features found in modern counterfeit bills. The ink on a legitimate 1950 bill may react differently with the pen due to its age, but it should not be mistaken as fake solely based on the pen test.
