If you aren’t up to speed on challenge coins and their significance – here is a link (opens in new tab) to the Wikipedia site  or if you are ok listening to a 20 minute podcast, here is another link (opens in new tab) to a Roman Mars discussion.

TRB will have a challenge coins made.   The numbers will have different meanings.
1 digit coins(1-9) will be special purpose VIP use only.  These identify people that have been a substantial part of TRB, and have made significant impact upon the mission.
2 digit coins(10-99) will be for the long haulers and do nearly the entire ride.  People who have dedicated so much their own time, effort and funds to it.
3 digit coins (100-999) will be for those that have made a substantial contribution of travelling for almost half the time on the ride.
4 digit coins (1000 and up) will be available for purchase while quantities last during the ride.

Graphics will be posted when we can.
