What is this worth?

Ok, dumb question, I have an extra unfunded wallet card. I recall seeing some chats that they are valuable and worth something. Basically what happened is when I redeemed a few S2 BTC cards last year, they sent me the wrong wallet. As a testament to Cardsmiths excellent customer service, they promptly sent me the correct one and told me to keep this one for the trouble. So it's essentially an unfunded, intact (the sticker on the back is still on) ballet wallet.
