Too bad it is the Deluxe=more expensive one. https://www.wizardcoinsupply.com/product.php?productid=1269
Considering both the third and fourth editions are out of print and often cost nearly that much when you can find a copy, I don't see it as being a premium at all.
That's not a bad price at all for a leather bound book . Plus I like my 4th Edition , now I'm looking for the Peterson book .
