IMHO “luxury” sets like this sell to wealthy guys who hire a decorator to kit out the game room in their new McMansion.
The budget allows the decorator to buy stuff like overpriced darts and pool and poker sets, and club chairs from Restoration Hardware, and a bar, etc. So the ridiculous markup doesn’t matter. Nor does it matter that serious poker players and collectors don’t particularly value chips like these. These might get used once a year if that.
So yes, I would not be surprised to learn that brand new, these go for $1K or even $5K or $10K … brand new. Just not sure anyone buys them used at even 5% their original price.
