Welcome to chip collecting!

I am strictly a collector of Nevada fractional chips, .25 and .50 cent to be specific, and I can tell you that they have almost become a thing of the past. The cost of making a fractional chip is typically higher than the denomination on the chip so it's almost a losing proposition for a casino. Most of the fractional chips you will find are obsolete chips and for the most part I do not believe you will be able to pick them up at a casino. If you're wanting to collect chips that you can walk into a casino and get in the future, I would go for the $1 chips.

Cheers!
Bill
