Should I sell my original Harry Potter sets or hold onto them?

I came across a good deal on four Sealed Harry Potter Chamber of Secrets (2002) Sets and was wondering if there would be any benefit in holding onto them for a bit longer. Another question do you think it would be better to sell them separately or in a lot together? The Four sets are , 4726 - Quidditch Practice (Sealed) 4729 - Dumbledore's Office (Sealed) 4731 - Dobby's Release (Sealed) 4735 - Slytherin (Sealed) Thanks,
