Chippers (poker)
Chips. Poker chips are small round discs used instead of money
at the poker table.
The ones used at casinos are typically made of clay, while home
poker games often substitute cheaper plastic chips. Using chips
instead of cash has a number of advantages, mostly just that
they're easier to count and manipulate. Color designations for
chips are arbitrary, but many casinos use white for $1 chips,
red for $5 chips, green for $25 chips, and black for $100 chips.
