here is an old thread about that card that was discussed here.
bobby had one that was graded an 8 a few years back,cant remember exactly what he got for it but i think it has $400. i have seen only a couple on ebay selling between $300-$400 and that was 5 years ago.
it has been asked a few times here on the forum if anyone would like to sell that card.
very tough to find and if you do find one the price will be high (if the dealer knows what he has).
i have one in my collection but it would take a lot of money to scoop my nrmt-mint one off of me.
also are you aware of the Jacques Laperriere all star card having two differnet backs,one with notations on the back of the Perreault puzzle and one without,
like the gordie howe puzzle which has the bobby orr card with 2 different backs,the laperriere card does as well.
