Nee help to Identify stamp

Twogun

I need some help with this stamp that I recently acquired in a small collection. If it had perfs, I would say it is a SC 156 because it has what appears to be a very light crescent in the pearl at the left of the numeral "1". the paper is a bit more yellow than the white paper of another stamp that is a SC156. Can anyone offer me an opinion as to what I might have?

A stamp that was off an off center "jumbo" that has had the perforations trimmed off so as to appear to be imperforate. That is, it has been faked. No value.
