The guide is off on most if not all older cards such as the 90's cards. I remember seeing a $20.00 card listed on Beckett sell for $450.00 to $500.00 on 3 different occasions. Beckett never changed the price to match this and that means someone not as knowledgeable on a card might be thinking he is getting a deal when he is getting suckered. Remember its opinion based a guide can't give you a person's opinion. Let's say I have been searching for this card for 5 years and when I find it I might not want to wait another 5 years and I bid 5 times Beckett value but another had a higher opinion than me and bid 10 times over Beckett I lose he wins. I would say trade what you're comfortable with if you both feel it's fair the guide shouldn't matter.
