Mel,
Also, just so those reading know how scarce a complete set of either year is...The Hard Rock destroyed the remaining chips each year. So, with only 200 made of the Derby Day chip each year, that means only about 100 complete sets are possible. Could even be lower as I am sure some received a Derby Day chip each year for making a bet & were not even collectors. Those single chips could be in the back of a drawer somewhere & not even in a collection.

Below are links to my account of how I did each of the two years when I got my sets.
