Kratz

Hello everyone. This is my first post on this for him and I'm glad I found you guys. I have a question related to the Royal Mint and a double Sovereign which is almost a half ounce of 22 karat gold. It arrived in horrible condition and I am initiating a return. But since they do not disclose mintage information I'm wondering if it's worth the bother. I imagine this coin will only ever be worth what the spot gold prices on any given day. Is there any numismatic reasons to send this coin back to them, knowing air quality is less than Stellar or should I just keep it and expect spot pricing for the coin? Thanks in advance for your comments.
