Up to now there were four color variations of the Harrah's Trump Plaza, Atlantic City, Bud Jones, coin insert $1 chip. The known colors are red, red/brown, maroon and brown. I think that I found a 2nd brown variety, much darker than the other one. It is last chip of the five. The last two chips are brown, no trace of red. You can see that last chip is much darder than the other.
