How Important is an Auction Lot's Description

[Exhibitman]

IMHO it matters and the buyer should have the option for a refund when the auctioneer is specific on a subject and there is no way for the buyer to know otherwise. In this case, the card is plainly labeled by SGC as an 1887. If I was looking at the lot and being told it is an 1890 by the auctioneer I'd want a guarantee it crosses to an 1890 holder, but the discrepancy is so obvious that I'd ask before I bid rather than bid on the assumption that SGC is wrong.

I suppose the converse question should be asked: is the auctioneer entitled to cancel a sale when the auction description is wrong and results in a rare card being sold as a common version? Isn't that the moral equivalent? And how often do people make posts here about great deals gotten on Ebay from ignorant sellers? Should those sellers be allowed to cancel those sales if they discover their mistakes?
