Good story on the Slew chips.
Fellow collector David Hench put me in touch with The Thoroughbred Owners and Breeders Association in Lexington, KY to get the Secretariat chips started. On Derby day after the release I read that Slew had died on Derby day.

I called TOBA and asked for information on Slew's owners. She gave me an 800 number.
I called and this message was on the answering machine.

"This is Seattle Slew, please leave a message and I will call you back."
