I know you think that this will promote the older casinos etc. I feel you need to think thru the consequences of your actions in the years to come as these chips get dispersed thru out the world. If there is not a prominate marking idicating that these are copies ( which I feel will destroy the look you are trying to achieve), then these chips will wind up decieving many future chip collectors as they enter the hobby. From the indication of your posting you would like to produce as many of these as you can sell ( who doesn't like to make money): this will just flood the market place with more questionable chips and I think we already have enough of them.
It maybe bad enough to chase people away feeling that there are just too many con men out there producing fake chips.
All in all it will wind up being a big bad mark against our hobby and be a detriment to it's future. Please consider the future consequences of your well intended idea and NOT follow thru on it. Thank You
