I recently purchased an 1859 on
ebay that I believe is a new unknown reverse die. Here is the
ebay listing to show the
ebay photos.
https://www.ebay.com/itm/164983349920The reason I bought this one was the die crack at leaf 14 looked slightly different from other leaf 14 die cracks and the stem to leaf 9 wasn't like others that had similar die cracks at leaf 14. I couldn't identify the obverse from
ebay photos, so I had to wait until the coin came to determine if it was new.
When I got the coin after about a 2 week wait, I looked at it through a loupe and saw that it was Obverse 41. Then I looked at the reverse and it appeared to be reverse E42 with unknown die cracks. So I was happy, at least it was a new die state. I set it aside until evening when I could check it out through my microscope.
Once I got it under the scope, It became clear that it was indeed a different die and not E42. The stem to leaf 9 was similar, but not the same. The re-punching of the 5 of the date was also different. I am still comparing it carefully to other reverse dies to make sure it is not a later state of a known die, but I am pretty sure at this point that it is new.
I've bought quite a few 1859's that I thought might be a new die and most of them turned out to be known dies. But this one turned out pretty well! I believe there are still some more new dies out there to find. I'm not sure how many, but I wouldn't be surprised if there are at least 10-20 more. Keep looking and happy hunting!
Here are the photos of the new die.
Here is the Obverse Haxby 41 early state with a fine die crack to the R of VICTORIA.

Here are two comparison photos from Haxby reverse E42 of the stem to leaf 9 and the 5 of the date.
