Take a mold that is already disliked by most people and has pretty low prices, then make the chip solid, hot-stamped, and give it a design that doesn't fit with any other set, and you've got the reason. Personally, I wouldn't buy these at any price, but somebody who's more forgiving to the Paulson chips mold or has a CDI/Classics/Pharaohs might pay around 75c/chip to mill them for a frac.
