Rick,

When a potential buyer looks at your auction, he doesn't know what you paid for the chip nor does he care. He looks at the face value, how much the chip rack is telling him it's worth (if he uses the chip rack)and how much does he want it for his collection.
The Chip Rack says the chip is valued at $5 to $9
What you need is someone to come along who really needs that chip to fill a hole in his collection.
With no disrespect meant, there are people on this board who have hundreds and hundreds, some over 1000 positive feedbacks. 19 is nothing to get excited about.

Good Luck,
Ralph
