Hello Same,
Nice stamp--thanks for sharing. It is either Scott/Unitrade #1 from 1857 or it could also be 15A or 15Ac from 1861-1862
There is already a thread on the differences which should help you determine which one it is.
https://goscf.com/t/33841#33841The Catalog Value is not a big difference ($150 for VF for #1, $200 for VF for #15A, $250 for 15Ac). Having the back be NH is significant more value.
Here is an image of my 15Ac, so that you can see how different they all are.
Do you have any more Newfoundland stamps to share?
