I'll pay 50 cents all day, every day for this card in this condition, as evident by the fact that this is not the first time I picked up this card from my LCS for less than a buck.
I have no idea what this card "books" for today but a quick look at a March 1991 Beckett tells me this card had a high book value of $65.00. The February 2010 Beckett (the last Beckett I've ever purchased) shows high book fro this card at $20. At that rate, maybe 50 cents is book value today.
Regardless, it's a great looking card from a great looking set and I'm happy to have it in my collection!
