Because of the smoother edge, the bi-metalled Brazilian Real coin would be an excellent selection when rolled at a fantastic surface like the jai alai court at Milford Jai Alai in Connecticut. This would be an interesting matchup. The coin should be able to handle its own for a considerable amount of time before the surface takes hold of the momentum.
