You seem to just have bought it for $300.
Similar domains sold in past:
somethingamazing.com ⇒ $295
somethingwonderful.com ⇒ $225
somethinguseful.com ⇒ $134
somethingbigger.com ⇒ $900 (but it was 8 years ago, so probably worth $300 now)
somethingperfect.com ⇒ $70
So I guess $100-$300 is about right value. Maybe if you hold it bigger price is possible, $1-2k.
