I think it would be a shame to only have one year (2004) on the tokens. Plus, the more we flood the market, the more likely it is less people will buy them next year.
That being said, there is a definate interest. This thread is only 24 hours old, and it is already filling quickly.
Also, if we made Mame tokens, and advertised them (not for profit, simply so we can make sure all are sold), plenty of other Mame related sites would come here.
Waiting to hear more from Santoro!
