Advise for vintage chess set being broken on arrival

I'd like to get some opinions on a suitable resolution for a situation I find my self in.

I purchase a vintage chess set. I paid a pretty reasonable price to the seller because it came with a nice patina, but was otherwise in great condition. I specifically wanted something with no breaks or heavy ware marks, and this set was exactly that. 

My problem is that the set arrived with a damaged queen and a very damaged king. From what I can tell, it was from insufficient packaging. An image of the king is below. 

The seller seems happy to work something out, which is good. And they have asked what resolution I'd like to see. The hard thing is what resolution is fair for them but also doesnt disadvantage me at all. I'm in my head I'd feel happy with a refund somewhere between an 80-100%, because this was not the set I signed up for. I'm just not sure is thats reasonable. 

I'm sure there has been hundreds of people finding them self in the same situation. If you have any advice, I'd like to hear it. Thanks

Are we talking about a $30 set? $300 set? Or $3000 set? Due to the seller's incompetence the damage occured. You are now inconvenienced and spending time on an item you might not even want anymore. Fairness to the seller would be the LAST thing on my mind. You are the buyer. What would make you happy? 50% partial refund might be a good starting point for something under $300. 

If it was me, I would request a full refund with shipping paid for by the seller. And be done with it. You seem like a more reasonable fellow, willing to accept the damage if the price is right. Good luck!

thanks, @pawnerai. The set was around the $350 mark. I updated the description to better reflect my feelings on the refund. i dont think I'd be happy with 50%, I'm actually not sure Id feel ok with 80%. I'm just a bit conflicted in whether I'm being unreasonable

But if you really love the set you might want to try to find someone to repair/restore the damaged pieces.  Could be pricey, of course, but if you just *love* the set...

true @grandpatzerdave restoration is on the cards. i dont see the set being thrown out.. But for now my dilemma is working something out with the seller. 

Once the partial refund is up to around 75-80% you really have to honestly ask yourself, do you really want the set at all in its present condition? I don't think you do. Once the spark is gone, the chess set will sit in a box on a shelf for a long time, until you one day decide to sell it and recoup the money. And then you're the one trying to sell a damaged set that you didn't really want in the first place. 

Return it and don't give it a second thought. This situation with the damage is all on the seller. They deal with returns all the time. 

I’m with @Pawnerai. I’d ask for a full refund and return shipping. Only you know what you’re comfortable with at this point. However, his point is well noted, you have a flawed set that you paid a good sum to receive. Selling it at a later date will be difficult to recoup as you will need to accept a lower price for a damaged set. The seller has the responsibility to make this transaction right. A reputable seller will do just that. Hope this turns out well for you!

In my opinion the king is very easy to fix if you have the broken piece, just with wood glue like titebond or white glue, you can get a fine finished join. Of course you've the right to asl for a refund.

I do agree with you @jacmater, the repair can be quite simple. If i had damaged the piece, certainly a good glue held securely in place would be my choice. But with a new purchase packaged poorly, I’m thinking a return is in order. Then again, who am i to say? The OP will make the right decision I’m sure.
