I have this pair of paper weights commemorating Harrah's 50th Anniversary. The picked up the one on the left at an antique store some time ago. It is a scarce chip but not rare. The one on the right was given to me by a Harrah's exec and is a very rare chip. I was just wondering how common the paper weight on the right is - are there lots of them out there or are they pretty rare like the chip. It also makes you wonder if perhaps way back in the vault somewhere there is a box or two of these chips just waiting to escape?
