Erik, I am by no means an expert on chip values and excluding any hard to find or get chips, along with the rising cost of postage, I have found that usually a $1 chip will sell for $2.50 or $3.00 and the $5 chips for $7.50 or $8. depending on the seller. Of course higher value chips will be a certain amount over face value even if they are closed casinos and cannot be cashed in. Hope this helps.
