I would think that they have the data. They definitely do for any transaction that incurred a FVF as that can be seen in your My Fees & Invoices data. That data goes back at least 10 years to when I joined and indicates that it is available for export from as far back as January 1999.
Transactions that did not attract a FVF may not show there, I never had such a transaction so cannot check, but would expect that is in eBid's database as a sale in some form.
