Hi Ralph-I collect Colorado strikes, along with the tokens and chips, and have David's 2009 chip guide. I dug through my emails and his email address could still possibly be: dniver@zianet.com. If you are looking for any strikes, do let me know as I may be able to help you out! Or, if you have duplicates or wanting to part with your, do let me know as well as I am still searching for some from Colorado. Best, Ian
