It is roughly 900 chips. They aren't worth what people pay for singles (if someone were going to sell the set one at a time, it might take decades to sell all of them).
I am guessing about value - say $0.75 to $1.25 per chip. So $675 to $1,125 for the set. The seller's opening bid is $1,000 - perhaps a bit high but close enough to reasonable.
This actually appears to be the buyer of the original listing, who just copied/pasted most of the listing/photos and marked them up from under $900 to $5,000. I get buying and reselling for a profit, but this is just disgusting. Dude is so lazy that he couldn't even make his own description or take his own photos. Hope he sits on these for a lifetime and gets less than he paid.
I could be wrong, but it certainly looks to be different sellers. The link I included above was the original seller, which shows that they sold via best offer about a month ago for ~$900. That seller was 'oducks' in Renton Washington, whIle the new listing with the inflated price is by 'guitarguy' in Baton Rouge LA.
