Turning the experts here...

I'm going to look at a collection in a few weeks, and one thing the seller has is a huge collection of Starting Lineups. I guess her husband bought them from the day they started, and never opened any.

My Q is: what would be the best way for her to sell these? I haven't even looked on ebay. Are they valuable, or did they go the Beanie Baby route? Does any auction house in particular seem to get good prices fore these?

Thanks, Ken
