Guess this one's up my alley as the resident Sedin collector in the neighbourhood
To me the dual auto jersey card is what I'd call the Holy Grail for Sedin collectors. It's definitely not a 1/1, but it is really tough to find. I've heard anecdotally (no idea how accurate it is) that there are roughly 20 copies - based on what I've observed this does feel about right to me. From what I've heard several are locked away deep in Swedish collectors' PC's. It took me several years just to find my copy, and since then I believe I've seen 3 more over the next decade or so.
While it doesn't have quite the longest odds of all time, it is kinda cool in that it is "the" card from the set, and with the overall print run of the product presumably being lower than a North American release, combined with many copies never having made their way across the Ocean, it's probably just as tough a find as any of those other ridiculously long odds cards.
For the longest time I believe it was the only Sedin card featuring their autographs on game-worn memorabilia, though 13-14 Prime had autographed game-worn nameplate of just Danny.
For anyone who hasn't seen the cards before, here's what the non-auto and the autographed ones look like... (and no, they are not available for sale or trade, although I've always been on the lookout for dual multi-coloured copies, if such a thing even exists).
[Edit] As to the value question - I'd be very surprised if an autographed copy became available if it sold for under $500... I'd expect one would command at least into the higher 3 figures, and who knows, if a bidding war kicks in perhaps north of 1k. I do recall one was on the market not too long ago, believe the asking price was something like $1500-$2500'ish - already having my own copy I didn't pay a whole lot of attention to it but all I remember is it wasn't snapped up immediately if at all, so that tells me really somewhere in the $500-$1500 range is most likely where one would sell. That being said if a dual-multi-colour copy should ever appear, all bets are off
