I don't have ERIC II yet but it's on my list. How does this book compare to other books. I have roman coins and their values by sear and the RIC's volumes on my computer. They have lots of helpful information, I also have the Whitman handbook of Greek and roman coins and the ancient coin collecting series by Wayne G. Sales which are all nice reading material. Is the ERIC II more like the RIC series? I've heard lots of good stuff on this book but just haven't had the money to spend on it yet.
