Have a look at David Lisot "cool coins" Starts with Stephen Hill and a nice Civil War Pound he values at £7,500. He says of great historical value. Agreed. Then a couple of US dealers each show their cool coins with IMO very little historical value or interest, but both valued at 200,000USD and 250,000USD a piece... Simply astonishing. https://m.youtube.com/watch?v=Iou4FHNDECk
