Silver Smith blue brass listed at an E ($15 - $19) rating in TCR (N6459) though I recently bought some for a couple of bucks each--I believe they are still in play--at least that's what a Wendover chap told me in March; the bicentennial Holiday In is a very desireable chip currrently listed as N1748 with a "K" value ($60-74) and I know people who have paid more than that. I have been playing at Harrahs since the mid '70's and picked up the bi-centennial out of a rack of chips as late as 1989. In the '90's a woman brought one in with her and the dealer wouldn't take it. I took it for face after telling her it was collectible. She just wanted some gambling money.
