What, if anything should I expect from the following situation?

About 2 months ago I came across a sales thread on another site (seller is not a member of this site) with a card I wanted. It was an spgu 6's patches that included my pc player, bobby ryan. There was no doubt about what card I wanted as it was the only one with bobby ryan in the thread. Unfortunately we did not come to a deal. Last week I sent the seller the following message "my offer still stands on the spgu 6's with bobby ryan" Seller accepted, set up a sales thread and I accepted. Card came yesterday morning and was not the right card. It was a spgu 6's jersey from a different year, but it did include bobby ryan. First thing I did was check the sales thread and he did send the card that he had put in the sales thread. Admittedly I didn't read it and just accepted it when it was drawn up. Turns out I am interested in the card he sent as well, but would have offered no more then 50% of what I paid for. The card he sent was not in his original sales thread and I had no idea he even had the card (or else I would have made an offer on both) So I pm'd the seller explaining that the card he sent was not the card I had made an offer on. I offered the possible solutions to fix the deal if possible:

I return the card for a full refund
I return the card in exchange for the card I made the original offer on
The seller gives me a quote on what he would have sold both cards for and if I agree I will send the difference
I made an offer of what I would have paid for the card sent and if agreed on he could refund the difference

I am hoping that the seller is agreeable to working something out but if not what should I do. Just it the card (at what I think would be a big loss) or try and file a paypal claim. I take some blame for not properly reading the transaction thread but to what point should I be held accountable.

Just looking to see what others think

So it's not the card shown in the Doughty sales thread he posted, but another SPGU Sixes?

If that's the case, then hopefully the buyer is willing to work something out. He technically didn't do anything wrong to judge by the sales thread, but in his shoes I would understand your confusion. You could open a Paypal claim but I'd only do that as an absolute last resort, since you don't want to damage your reputation.

I certainly dont think the seller did anything malicious or intentionally deceitful, and yes it was a different spgu then the one in his thread, a jersey instead of a patch
