This is my new interest area. The problem is that there are MANY factors. 1. Dates - at this time I'm not paying serious attention to the Braided Hair issues (1839-1857). 2. Identifying Die Varieties (Newcomb Number) -- I'm currently using books by Noyes and Wright. -- The Braided Hair issues (1839-1857) are on the back burner for now because there are often many die varieties per date (30-50), many of which take require coins graded in the MS 63-65 range to identify. (I also have Grellman's book which I'll use later to help with these coins.) -- Images from online auctions often leave much to be desired for IDing varieties. 3. Grade - Strictly a function of price which means mostly below MS; I'd like to get VF to AU. 4. Rarity - I'm using the Noyes' books to guide me in this. 5. Value Source - I'd like to find auction results tied to grade and Newcomb Number, but's easier said than done. Right now I primarily use the Greysheet but it doesn't tie in with Newcomb Numbers nor rarity very well. And I haven't investigated PCGS pricing. I'm looking for suggestions as to how best to price a coin. Currently I'm using the Greysheet and trying to match it with a coin's description. What do you do IF you can ID a coin's grade AND die variety?
I would use the PCGS price guide as a guide. It seems to have the most extensive listing of Newcomb numbers in brown that I have found. There are Newcomb numbers on PCGS that are not listed for brown but are listed for red brown and red. PCGS does have auction records by Newcomb number. CAC also has a price guide of brown cents by Newcomb number. https://www.cacgrading.com/
What about EAC Auction records. Those are always listed by die marriage numbers and I think you're a member, aren't you?
