The FDOI was just 5 days ago. Most FDC's these days are not available until a month or longer after the first day of issue. People creating FDC's have 60 days from the first day of issue to send their covers in for cancellation. Once those start coming back, you'll begin to see them on
ebay. Wait a month or so, and then start watching. But it could be two or three months before we begin to see a lot of them.
