Hi everyone - I just sold a bag and am required to mail out to authenticator in Nevada. Any tips for making this successful? The total was $1700. I don't see a place to purchase insurance for that amount in the postage/label print. It just says since your item is over $750 dollars that I must use signature confirmation. I am concerned just sending this priority mail with a signature required. Then again, I am confused -- am I requiring a signature of the authenticator or is that for the buyer? I know the authenticator ships directly to the buyer. Any advice would be appreciated.
