Hi John,

As long as the notes only resemble real dollars in size, as long as they are non-negotiable and state so on the face, AND, while the intricate designs are similar to US currency and necessary for the same security reasons, nothing on the samples that I've seen come close to looking like real money. It's obvious that to do this, the casinos must print their currency on different paper, no dead presidents are pictured and make both sides of the notes easily identifiable as not being real money in print. ...not much different from $1 tokens vs Ike dollars.
