Robert, I sold all my doubles in the past few weeks. You would be better off selling them one at a time. I admit, it will be time comsuming, but you will get a "total" higher amount. I sold mine in groups of 8 and tried to place a chaser in each one. The results were that I average about $11/strike after all the dust settled. If someone really wants a strike badly enough, he will bid accordingly. Look at the different auctions and see what groups are going for. The bottom line is this, less in a group, more money selling piece meal. This is my opinion!
