Tony, Also some casinos will only let you get $1.00s at their crap tables, (as some use tokens at the BJ tables or roulette), (Especially small casinos) If they have only a $5.00 min game, sometimes they will only give you $5.00s. To get $1's here is a trick that you could use if you ever need: $5.00 min game? Tell the dealer to Place the 6 or 8 for $6.00, put down $10.00, and he'll give you $4 in $1 chips. Just a little tip to use, especially if you decide to collect smaller casinos in Las Vegas (Had to do this at the Speedway in North Vegas, they have two varieties there, a Hot-stamped 1 and an inlayed one.) or other Nevada hotels. Hope this helps.
