What’s the most expensive horse you’ve ever purchased?

As the question says…please state currency as well.

I’ll go first…I’ve never purchased a horse for more than $5k Canadian (around $3500 USD right now). Currently have 7 horses on my farm…purchase prices were $800, $850, $1200, $2600, $3000, $4250, $5000. Five out of seven were babies I trained/am training myself.
