Thank you kindly Jwt! I love helping out fellow collectors and I love getting to see everyone's collections and hard work. We all put a lot of passion and energy (and money!) into this hobby and I am really happy I found this place to discuss this stuff. It's finds like Noob's that make this stuff so exciting!
I am really happy for you bud! These coins are very tricky and without really studying them and spending a lot of time looking at many many examples, you can see that this was not known by numerous people who are fellow numismatists. You had a detailed provenance going back a while and no one noticed the pellet in the N. I am not saying it is worth a fortune, because Edward I pennies are relatively common and there aren't many who specialize in them. However, be feel proud to owning a great, rare coin.
Doug, The orientation is of random rule on a lot of hammered English coins. This is because there are two separate dies used to form the coin. The obverse die is held steady by an anvil and the reverse is held in the hand of the striker and that reverse can be held in any orientation at the whim of the striker. Thus zero consistency.
Thanks. Since we start the obverse with the top of the head It seems right to place the reverse so it reads from 12 o'clock clockwise but that still leaves the question of CIVITAS being before or after the city name. I would expect collectors to have a convention to make it easier to alphabetize results.
