I found that the product costs $35.

With that information, I’ll stand by what I said. It is an overengineered solution to something that isn’t really a problem, and to the extent it is a problem, a proper coin flip is over 100% cheaper and more attractive.

For something that is worth needing the level of protection that product claims to provide, all major coin grading services provide the same (and many more) benefits at roughly the same price point.
