For this question I deferred to a friend of mine who is a blackjack dealer in Biloxi, here is what she says:
Every casino differs as far as tokes however there is somewhat of an average. Your typical dealer will average anywhere from $9 - $11 in tips and makes an hourly wage of $4.50 to $5.00 per hour. So I always like to think we average $15 an hour. Some of the bigger casinos like the Grand and Beau Rivage, however, make more than that. Their toke rates stay at $14, $15 and $16 per hour so they make close to $20 an hour (that's including their hourly base pay). You only get benefits (insurance, 401-K) if you are a full-time employee. Some casinos will make you a full-time employee automatically after 90 days while other casinos will keep you part-time until full-time positions are available.
