Three varieties on this Northern Nevada $2.50 chip. No fluorescent features on any of them.

The original from the 1970's had no line under the .50 and was supposedly confusing to the casino personnel. It has the H&C Short Cane mold and is shown as the chip on the left. TCR 2515.

There are two reorders several years later, one with Short Cane mold and a thin underline, one with a thicker underline and the Long Cane mold. TCR 2515.1 and 2515.2

The original no-underline chip is considerably the scarcer of the three, particularly in unused condition. The thick underline chip is used, VGD and doesn't stand on edge. The thin underline chip is AU and stands on edge. These are in my snapper collection and were upgraded several times as I came across better examples

I offer the original on the left at $30 and the other varieties at $12 each. If you want all three, it's $45 total.
