Yes, it's me. Sorry for the long hiatus. If you look in your red book right now, you'll notice three listed varieties of 1819 cents: The 1819/8, the large date, and the small date. However, there is a distinct fourth obverse variety listed as Newcomb 10, but not mentioned in the red book. Here's a picture: As you can see, the date is very wide and the first 1 is very far away from the 8. Both the obverse and reverse dies are only used on N-10. So why isn't this listed in the red book? It's a scarcer variety but it should be listed like the other three, shouldn't it? Even though it's scarcer you can still find it unattributed on Ebay pretty easily.
It's not my coin though. Yeah, there isn't enough room for everything. I wonder if anyone with a Mega Red Book can weigh on this. Is it listed there?
In the first Mega edition it mentions that there is an overdate coin(N-1). Then it has another entry listing for N-2 thru N-10. It lumps these nine varieties in one price listing. It does come with a disclaimer that scarcer varieties may cost more. The first edition doesn't even mention a small and large date. Nor does it show a proof coin for that year.
The five scarce ones are, in order of highest to lowest premium, N7, N4, N5, N3, and N10. Everything else is common. The N10 is by far the easiest to identify of the small dates, however. N3 and N4 have a very close date, but different reverses.
Well 1819 has the large date (two dies N-1 and 2) N-1 is also the overdate. 3 through 10 are all small dates. N-3 and 4 (one die) have a small date with stars very close to the date. N-5 through 10 have a small date with stars distant from the date. As you mention N-10 has a very wide date, but it it isn't really that different looking from N-9 with has a wide date. Only real difference is the distance between the 1 and 8 is a little wider on N-10 than N-9. SO you could expand the 1819 listed to Overdate, large normal date, small close date with close stars, small close date with distant stars, small wide date , and small very wide date. Problem it you can do something similar with many of the middle dates and explode the Redbook listings.
It does have extra listings in the large cent area that I have compared with an original type RedBook. For example there is a listing for a proof version of the 1819 cent. That listing is not in the smaller version Redbook. Of course, the mintage number for the 1819 proof is two. Only one of the two has been graded (PF64). I believe it went for $32,000 in auction. I prefer the Mega RedBook for the extra info. Each edition has different information in the appendices. One of the appendix this year is about all the coin operated machines that used a nickel to operate. I recommend buying the Mega. If you check around later in the year they may go on sale. This year I bought two by getting in on a pre-sale that was pretty close to a BOGO.
