Have you actually sold any chips at those prices? While America is a free market, and you are free to buy and sell things for whatever you like, us collectors call that price gouging. You are intentionally listing chips for sale at a price that far exceeds the actual value. This is especially relevant since you are even aware of this. The only thing you can hope for by making this post is to take advantage of newer chippers who may be unaware of their real values.
Taking advantage of those less knowledgeable is not a good way to make friends on this board.
