I dont know the mintage on them and maybe they are less than newer releases 10 years later but people like them and arent willing to part with them. Look at the bucket of blood chip, it sells for a huge amount, I think I paid about 140.00 for it but they are surfacing on Ebay more and more lately and I have seen the price dropping on it. Maybe someone more knowledeable on this will post more about pricing but my Dad always told me that it is only worth what someone will pay for it and I guess the question is are you willing to pay?? I recently saw 2 ZZTop Hard Rocks that were mint and only 30.00 each and that seemed like a good price to me.
