In October I had a rare signed LP to GSP go missing , noticed today another user sold it last week?

Royal Mail wouldn't compensate even though I sent it signed for as they never scanned it. It was a signed album and easily recognisable as it was signed in biro by all the band.

Is it worth pursueing or should I just shrug my shoulders about it all?

The items are identical.
I've already refunded the buyer.
I used the Parcel Post option and this was before the Post Office determined that you had to have item scanned at a Post Office to be valid if sent signed for, befor they they were automaticall scanned at the sorting office.
Just an odd situation, I've emailed the recent seller to find out where he obtained it from and then put this message on here,

Unless you can prove that your album was the only one signed by the band, you obviously can't prove that it's yours.

The rest of your post is unclear, so take whatever applies from the following:

If the package never reached the GSP hub in Lichfield (ie. tracking doesn't prove delivery), then lodge a claim with Royal Mail for loss in transit with your Proof of Posting receipt once you've refunded the buyer. Unless you bought the wrong postal service (one that doesn't fully cover the item's value) or the item is on Royal Mail's 'exclusion' list (not everything is insurable), you'll be fully compensated.

If you failed to obtain a POP receipt  at the Post Office (which I find hard to believe for an item of this supposed rarity),  Royal Mail won't compensate you, obviously, as you have no proof that it was ever posted.

If the package was lost after reaching the GSP hub (tracking proves delivery), then that is not your problem.  The buyer's gripe is with the global shipper.
