Is there a difference between the $1 chips issued in the $1-$5-$25-$100 set versus the $1 chips in the $1-$5-$25 sets. Based on what you write and what I can gather from www.cochips.com maybe the #'d chips above 100 went to the $1-$5-$25 sets? Also can you confirm the 100 un-numbered chips - www.cochips.com shows 500 produced. Thanks for the info!
