Poker chip values?

[JimGil]

I'm getting custom labels made for my dice chips. I'm going to use the following values for the chips, but I don't know what value to assign the blue chip.

White - $1
Red - $5
Green - $25
Black - $100
Purple - $500

Blue - ???

I would think it would be $10 or $50, but it seems like a waste becasue you could just use 2 reds or 2 greens.

Any ideas?
