I thought of that, but with collectible items such as coins (that's what I have on eBay right now), the collectors usually have the money when hard to find items become available. Often, it is the times when you think this isn't when something should be sold on auction that turn out to provide the best return. Oh well, I'll wait and see what happens when the auctions close.
It's funny because I checked on Christmas day and New Year's Eve - times when you would think there wouldn't be many on eBay - to see if there were a few "deals" available, but everything was closing at good prices.
