1846 Large Cent Tall Date Line Through 1 N.13? 23? 25? 26?

I agree with your findings. A quick look at my Grellman book narrows it down to N-13, N-23, N-25, or N-26.

Can you see a spike from the dentils through the right top of T in UNITED? I think I see something but it's not clear enough. If so, this might be N-23. That's a guess by an amateur!

I'll try to look closer at the reverses later today. As you know, the late years are not easy to attribute so we may need an expert.

worst case scenario you have an R3 on your hands.

I don't see anything and because the coin is porous many of the detailed markers may not be visible. Maybe you can pick up one of these based on having the coin in hand or someone more talented than me can help.

N-13 Are there lines joining 'U' to the ribbon tip?

N-23 Other than the spike I mentioned earlier everything else is minor and may be hidden by the porous surface.

N-25 Is there a short spur up from the right top of the first T in STATES?

N-26 Is there crumbling filling the N of UNITED and perhaps joining NI to the leaf below?

I just want to mention that the Grellman book is great and well worth the money. Bob sells the book directly. I actually got to have a brief phone conversation with him and he is a great guy.

There is a line up from the first S in States if that helps!

Took some close up pics of certain points on the reverse, and just sent an email to Grellman. Hopefully It can be determined. The coin is not mine, Just trying to help a good friend!

I will second the Grellman book, and the Newcomb book, and the Noyes volumes! Just won my first Noyes volume on ebay tonight - can't wait to get it.

I think I got a steal on it, as I've been looking for quite awhile for a set of the Noyes books, $78.25 for the 1816-1839 volume (Red leather cover). Most times I find them they are priced at $100.00+ per volume. Got it from Kolbe & Fanning on ebay. I bid a little over that but won at a fair price.

My EAC library is growing pretty quick. The Grellam book is fantastic, and I am slowly going through the Newcomb book, a bit harder to read as it's hand written. My favorite EAC book so far with out a doubt is Manley's Half Cent Die States - that is the bar all variety books should be written to achieve. Breens Encylopedia of Half Cents is also pretty good. Looking forward the the Noyes books as I've read so many good things about them. I feel before I go off into buying EACs I should up my knowledge quite a bit in this area.

My numismatic library is already pretty large around 700-1000 books, and auction catalogs (and I sold or disposed of more than 40 file boxes of auction cataloges, after many years of carting them around). I did manage to keep the most of the really good ones though. That was pre Internet days, and I couldn't give them away back then, no school or coin club wanted them, same went for an almost complete set of Sky & Telescope magazines (now early copies sell for $50.00 and up on ebay)! I put them all into a paper recycling bin, ouch. Oh well live and learn.

I already have a hand full of them to attribute. I find the late dates quite difficult if they are worn much beyond a nice VF, even then they can be tough. I will be joining the EAC in the near future (something I should have done decades ago)!

Lately my collecting has been almost all numismatic books (not a bad thing either). As the really good reference books seem to keep creeping up in cost, might as well shoot a few of the better ones down now before the become unobtainable, and unaffordable

Been thinking of dumping my Morgan dollar VAM collection to raise funds in the EAC area. I see Morgans as coins that will always be available in the future, but the early coppers are getting really hard to find and the cost has begun to sky rocket. Besides they have a certain history I enjoy and copper is more pleasing to me as a collectible anyways.
