Are the CAT 623B hammer prices free to read?

Hammer prices are what the auction house recorded when the lot closed, before the buyer's premium, in the currency of the sale. A sale listed on a house's own site and on its platform counts once. Doubt a figure? Open the sale and its listing is linked there. How prices are recorded.
