I don't think the name and the extension are a good match. The name however is a short and easy to remember word. Developmente might increase it's value. For the name alone, I would say mid to high $xx, possibly very low $xxx.
i dont like this extension but i see some people here are interested in it so i searched and found that the most appropriate domain name with gold is(up)because people in gold...stock and forex market always declaring that the market up..the market down..i spent 5 years in forex market and i know what i am talking about..but i still dont like the extension
