For that sort of money you would have quite a few doubles to choose from.
Champlins has had a 475#2 Jeffery for a while which is priced at 15 and a half.

For the $18,900 price tag you could buy a Boswell 500 NE once owned by J.A. Hunter. A better cartridge in a rifle with history.
The 475#2 is a great cartridge no doubt but the 470 is much simpler to work with at the reloading bench.
