Today I purchased a Key Chain With a GN 100 dollar chip encased with 2pcs of plastic.It appears to be TCR# N4456.Im debating whether I should remove it from the ring.The plastic does have some chips on it.Does anyone know if this is indeed an actual chip or something that was sold as a novelty? The only thing throwing me is TCR has an N for logo and this appears to me to have a logo.Golden Nugget is circled around the 100.Otherwise it matches the books description.What do you think I have?Barry
