I actually purchased the $5 Dillinger's chip at the CC & GTCC convention this year and saw the $1, $10, and $25 at the same dealer table where I bought the $5 chip. I actually paid $9 and I believe the other chips were all priced the same. You can try to check with this same dealer to see if he has what you are looking for by checking out his web site
http://www.rollyschips.com/, unfortunatley right now, his web site is incomplete and the "contact us" link doesn't work either. Maybe a more established CC & GTCC or Chip Chat member may know how to get in contact with him. I hope this helps.
Good Luck!
