Now that is an interesting idea. Would it be possible to take it further and make a strike with the profile of the $10 strike but with a solid gold center with an outer ring of silver??? Not sure if the metals would work together but I bet, no matter the design (no color needed), that would be one nice looking token. The look would be similar to the 4Qs 50th anniversary strike.
The casino can work out the odds but if the content value was kept at the level you suggested, a player could win one similar to the forty process, perhaps diamond, diamond, strike. They could be made available in the cage similar to the 300 process, and lastly, be available as a reward at the players club.
