I have a batch to submit, and have settled on Anacs for various reasons. Upon what source do I base the declared value for shipping/insurance? Greysheet? Redbook? PCGS? Further, what do they do if the coin I think is MS63 (PCGS $385) is in fact MS66 (PCGS $4000)? Or the other way around? Help a rookie out here.
Use the $ amount you'd be willing to sell the coin for, so if it gets lost you have enough insurance to make you whole again.
