Make me an offer by replying to this post. There are 18 chips and quite a few are very rare. The 20,000 chip is in great demand and I only had 5 to start with. This is also the last of the $5000 chip. The yellow $500 NCV chip was previously unknown until a couple weeks ago. I still have a few duplicates of most of the rest, but this is a great lot to add to your collection.
