Dan,There are TWO $10s and Two $40s at Harrah's/Harveys in Tahoe.
At Harrah's the $10 has the "New Tram" to Heavenly Valley.
The $40 has a Snowboarder.
At Harveys the $10 has World Series of Poker.
The $40 has World series of poker-Ace/King of Spades BIG SLICK.
All coins are labeled Harrah's/Harveys, Lake Tahoe.
and the $40-s are blue cap and colorized.

(In Poker,Texas Holdem,when your delt the first two cards and
they are the Ace and King of Spades,Your holding BIG SLICK.
This jargon is used on various sets of cards.)

While at Harveys member #1053 played for the $40 token,
It is used as a gook luck token when placed on your two cards
indicating your going to call or raise the bet.
He showed me the tattoo on his arm...BIG SLICK.

Watch the World Poker Tour on TV, Travel Channel, Wed nights.

I hope this helps answer the many questions.

P.S. I think I will switch to Poker.
