mugen/momo horn button

[dove grey 64]

Hey guys wondering if you can shed some info on this horn button. Trying to work out if its special in sone way as all the ones I can find online have "mugen power" and this one just says mugen.
Came with a mugen wheel made by momo

^correct, I sold that wheel, this was its button.
Im going to offer it for sale, seems like genuine ones are asking $50-70 on ebay.
What would be a fair asking price?
Cheers
