They are quite vague on what their “Mintshield” technology is; I guess it is proprietary. Is it a coating or coin rinse or something else? At least they are brave enough to bring it on stream. I hope it works because that will calm down fears of white spots amongst numismatic Silver coin collectors.  Thanks for information.
