One is attributed Large Date and the other Small Date. I see them both as Large Date. What do you think? Labeled Small Date Labeled Large Date:
The style of the date resembles the large date on both, however the '4' is not almost touching the '8' or '0' (especially the '8') on either of yours. I was looking here at the comparison pic: http://www.pcgscoinfacts.com/Coin/Detail/1823 and then here is my large date where the numbers look like they almost touch. Very interesting. I'm a rookie here, just making some observations. Edit: If you check this page and scroll down, they give more detailed info on the date differences along with the same comparison pic. http://www.pcgscoinfacts.com/Coin/Detail/1820
Thanks for the input. I'll call NGC and see what they say. And I'll report the answer on this thread.
They are both large dates, There are six different large date dies for 1840, and five different small dates. All three coins shown so far in the thread are large dates, the second is N-10, the third is N-7. I haven't been able to determine what the first one is. It might be a early state of N-9. It definitely isn't a small date. This is what a small date looks like. Notice how close the 1&8 are on the large dates, they are distant on the small dates
The large date seems to be much more common, and I agree that both of them are large dates. Here's my humble example, nice detail, but an old cleaning rendering it unnaturally red. I'll replace it at some point.
NGC's response was IF the attribution is in error they will correct it for free. As for S&H I pay to ship to them, they pay for the return shipping.
