I received this set of chips from the Biloxi Belle today and these, I believe, are from the backup set. The $1.00 chip is listed however the $2.50 and $5.00 are a new find. The $2.50 chip has 6 green and 3 blue inserts. The $5.00 chip has 4 Peach and 4 gold inserts. Jame's book shows the $1 and $100 from the back up set however states "NO other denominations yet know." I would like to know if any other Riverboat collectors have seen or possesses either of these chips. Maybe they are now know??? Thanks for looking.
