Also the two with the hub and octagon inlay are rather uncommon. (heck I'm talking uncommon for a store chip now) The 50c was a later issue, maybe in the last two years, so there might be less of those floating around.

You can usually find the same chips in a bargin bin for $2-3 each, or about the same price. But the easy part is, if you want a complete set, you might be talking about the only person who has them.

The $1, $5, $25, $100, $500, $1000 are easy to find. The other three aren't.
