Amazing, you have found some incredible treasures. That hammered gold coin is one of the nicest I have ever seen. Please keep posting, and if you make a really significant find, please post in the Today's Find section so more people will see it!
Jeff,
While the Rules preclude the OP's finds from Banner consideration, do the Rules also preclude the OP from an Honorable Mention acknowledgment?

Unless it was in a boat, car, truck, SUV or bus and possibly a bicycle, I would not make it there. You only have to slide sideways down an Airport runway twice in an airliner (passenger aircraft) to break you from flying!
I'm going with the theory the banks were closed that day, so those folks buried what they had. Particularly before a battle or a siege. Rather like the hoards of Roman coins found in Britain, or the Viking plants.
