PC Gold q9 eternal blade

As it is now:

Eternal Blade of Swordsmanship
15-22, req 9
Swordsmanship +1 (chance 19%)
Inscription: Strength and Honor
15^50

I have seen higher req eternal blades offered on guru auction at 330k - 550k ...

so it seems, for once I might have hit my jackpot. I could add a +20% enchantment mod to this blade right away, but all I really wanna know because I don't follow the market, what is it worth today as it is?

Thanks.
