1820 Shilling H over Horizontal H question.

[Unwilling Numismatist]

Good day, hive mind. Is there an example anyone can point me to for reference of the said variety? 

I have one I would call "similar" but it would appear as it is quite abraded more potentially to be a H over Horizontal N. I have considered and referred to as many abraded 1820 shilling coins as I can find on the likes of Ebay, past and present and all of them show clear spacing between the bars of the H, even when almost flat, so I believe this one is different.

I would appreciate any thoughts on this.

Its so scabby I weighed it. Its only a little bit light   5g exactly. Fake 100%  but I think contemporary rather than modern as it came from a neighbours fathers estate a few years ago.
