Look I'm wiling to fight anyone who doesn't think Toussaud is the greatest broodmare of the last 30-40 years.
First she was a grade one winner of half her starts.
Second, she produced five graded stakes winners from five different sired.
Third, she is the mother of both Empire Maker and Chester House. Empire Maker stands for $100k now. Chester House died suddenly but in three crops had two Breeders Cup winners. He would have been a $50-100K sire.
If Chester House had lived another decade she would have created about $200 million in revenue for her owners. Empire Maker alone may bring them $100 million. You literally couldn't put a price on her value.
