A bill that was incorrectly cut so that part of the image of another bill is visible is called an alignment error. While these are quite valuable depending on how much of the other bill is visible, retail prices are in the $600 - $1000 range for most specimens.
Note that bills are not considered valuable if they are only slightly misaligned, with a wider border on one edge but nothing visible of another bill's image.
99% of the time a 1950 $10 bill is just worth $10. If it is an error, star note, or in perfect condition it could be worth more.
