I think it's probably next to impossible to accurately identify a bean variety by the pattern on the seeds, there are so many that are similar. You might want to contact Russ Crow (the Bean Collector's Window guy) and ask him what he thinks; he might know if Red Marbles is also called Red Speckled, or maybe will have other information about Red Speckled. He is really a bean guru! Good luck, and have fun with the bean sleuthing
