Paul, check the results of that dutch auction again. Charles bought 23 of the 24 chips available, so the original seller has no more of that particular lot. (However, the original seller may have others which weren't offered for sale.) If the large-key $1 chip were sold as a single chip, I think it would attract buyers at more than the $3.52/each when bought in quantity. My $5+ estimate was just my personal opinion of a price which would be of interest to me for a single chip if I were looking for it (which I'm not). However, Charles is free to set any price he wants for them, and buyers are free to accept or pass on whatever price they feel is attractive.
