Howdy everyone. I got these questions sent to me privately. I don't even recall the last time I submitted anything to anywhere, so I'm not the best person to answer.
That sounds right, the higher the value of coins submitted, the higher the S&H for insurance purposes and all. All coins are shipped registered, insured, and requires a signature.
nothin stupid about those questions, we all have to learn sometimes and other people's experience is a great way to learn!
