NO!! it’s worth around $1700 - $2000.
I say that the mask is worth $1000, the original price. Your nuts if your gonna make someone a $5500 profit!

If you like the mask and can afford it, I’d say it’s worth it… but like any collector’s items, you could limit a turd and if it’s priced high enough, some will buy it.
