It's a nice piece, but for me, personally, I couldn't say "it looks almost identical". The movie version is Tatopoulos, the TV one is smaller (IIRC) and doesn't have the same impact design-wise, for me at least, can't speak for anyone else. Just a personal preference.
But I absolutely think you should do a run. Anubis helmets have sold at reasonably high prices, e.g. the cheaper of two recent runs was $900 without a headpiece. I wouldn't be interested myself at that kind of price for the TV version of Ra, but likely would be if you could manage a lower price.
(For the movie one, I'd be in like Flynn - halloooooo, new owner of the Propstore piece?) :lol
