USPS Shipping Insurance Question/Help
 

This is the first package I have ever had lost.I sent a package to SGC for grading and the post office has lost it.I dropped off three first class packages and the one insured priority.All three first class showed all the tracking steps across the country.The insured one never showed anything other than being accepted to the post office on the tracking.How easy is it to file the claim?Do you have to have receipts for the contents?Anyone who has filed a similar claim I would like to hear your experiences with the collection of this insurance.Thanks for any help on this matter.Jason
