Legal question about mail insurance?

OK I recently sold a high dollar comic but when the buyer recieved it, it was water damaged. I was asked to send the original insurance ticket to the post office in NY which I did. The buyer then canceled the claim through the post office, filed one through paypals, and returned the comic to me with delvery confirmation so paypals would give him a refund. The problem is the NY post ofice gave him the insurance ticket and now the PO here in IN is refusing to file a claim since I don't have the ticket. The thing is I was asked to send the ticket to NY by the post master for the NY office and I didn't send the ticket directly to them I gave it to the post master at my local post office who sent it as an interdepartmental letter to them. I have a copy of the ticket but they say that's not good enough. Personally I think is was just a scam by the 2 post offices to deny the claim. I think the ticket was given to the buyer on purpous so I couldn't file. what legal options do I have?

I did specify that any damage would have to be taken up by the buyer but the problem is paypals doesn't see it this way. No matter what paypals says it is the sellers responsibility on everything. Paypals told him to send the item back with tracking and they gave him a full refund no matter what I said on the matter.

Sounds complicated - i don't think yahoo answers is going to help you

Did you send the comic FOB seller's location? Then it would be up to the buyer to pursue the remedy.

Try to get the ticket back from the NY post office. then call a lawyer

I think you may have to chalk this up to a lesson learned. Next time when shipping something so valuable, make damn sure it can't be damaged!
Or next time, stipulate you are not responsible for what may happen in shipping. That way the receiver will have to deal with the shipper company(P.O. etc.), and not you.
