Supply and demand. It'll never be one of the comics worth thousands because, as you hinted, marvel do a lot of those kinda things. But, if you hang on to it until they stop being dished out and happen to find a Brooklyn fan who digs comics/misc paraphernalia who doesn't have a copy then odds are you can make a few quid. If it sails up near the £50 mark I'd be very surprised. If they become rare and an avid collector wants one, I'd still peg the value at around £20 maybe, tops. A pristine Walking Dead #1 will fetch a couple hundered now and that's (as far as I'm aware) about as high as "new" comics are going just now. Kick Ass #1 is also being peddled for up to the hundred quid mark but it's only WORTH that if someone'll pay it. Rangers/Celtic merch tends to become valuable because there are a lot of die hard fanboys who'll blow money on anything with the logo on them. If Brooklyn Knights are the same way, then go for it. Otherwise, I'd imagine the ony way it'll be a 'real' asset is if you can get it signed by players/coach etc. xx
