Underneath the tab called Market, there is Marketplace. You can look at Auctions and there is a drop down menu to scroll through and select Irish Cobs to narrow the search down.

The other option is Random Sales, same place as Auctions, which also has a drop down menu so you can scroll through and select the breed you want.

3rd way is up top along the tool bar is a magnifying glass, clicking on it will bring you to a Search function, you can use the drop down menus to refine your search a little bit better, just make sure to input minimum sale price of $1.

Thank you!

You're welcome and added in the 3rd option!
