Are Souvenir Sheets Worth More Intact?

Hi everyone,

I ordered some souvenir sheets from the Canada Post website. In terms of long-term value, are souvenir sheets worth more intact? Would it make a difference if I removed the stamps from the souvenir card?
From what I have seen, most Canadian stamps within the last 30 years hold their face value, but rarely more. Seeing as how the sheets I ordered were only a few dollars each, I'm not expecting a sudden increase in value.

Thanks for your input!
