USPS lost my card submission to SGC and denied my insurance claim

[CTDean]

I have made two insurance claims in the last few years and was paid within a week both times. For proof of current value I downloaded a recent auction result or sale price of an item like my damaged piece. For ungraded cards it
might be a little tougher. Try to find sold cards that match your cards condition and for each cards value on the submission form.

Since your package was scanned at the Post Office and then went missing I
would also file a form with the USPS Postal Inspectors in D.C. The forms are
available on their website. Postal Inspectors will forward your complaint to
the Postmaster at the site of the lost package and he will have some paperwork to do. This has worked for me three times when carriers failed to
scan an insured package upon delivery.
