Can you reuse postage stamps if the Post Office doesn't stamp them?

I have gotten many items in the mail, especially large boxes with several stamps on them, that seem to have not been stamped with the Post Office mark. I know that the stamp from the Post Office invalidates a stamp for further usage but if they are not stamped at all, can they be used again? Do they have any mysterious way of marking the stamps that I cannot see but they will find if I were to try to reuse the stamps?
