Originally the seller had the auction title and description stating "Luxor" chip, while the chip in the picture was the Excalibur chip. This was the original listing:
Item name: $5 Luxor Las Vegas "Frost Dragon"
Item number: 6237235845
End date: Dec-24-05 11:11:31 PST

Later he corrected it so the title, description and picture all say Excalibur.
