Most recent sale of "Owner" first (ownersclub.com) was 2015-12-02 for $815, roughly six months ago.
"Price" at the end is more promising, seven more sales. The latest a few days ago, instaprice.com for $122 and two more this month, discountedprice.com $138 + reducedprice.com $405. The highest being domainnameprice.com for $3,291 and gold-price.com for $1,667 in March and Last October.
With this in mind and the right marketing I'd say at the very least $100.
