The Las Vegas Club and Horseshoe are relatively 'common', I'd put the price somewhere in single digits. The Eldorado, Frontier Club and Fremont are less common...maybe double digits. NOTE: pure guesswork on the values...I honestly don't remember what we paid for any that we bought, one was a gift, a few were received in a chip trade.
My very favorite encased cent...bought it on ebay, and really really wanted it, so paid more than we wanted to, but we've never seen another like it
