There is a seller on ebay selling a bunch of Silver Slipper $.25 chips. I asked him about them and he said that he had a box (100). He has sold 9 already, has 35 listed now and will be selling them "little by little to see what the market is". Although 35 for sale at once doesn't seem "little by little" but whatever.
