Godaddy tends to over-exaggerate prices in their appraisals.
I think it's roughly worth $500-1500 although i am not completely certain with that estimate considering i would never buy a .mobi. But that is a personal preference.
I cannot think of a likely end user for this domain, and it's not a particularly attractive name for a reseller. Youngest*mobi domainer value is about $12.
Most likely not worth much now, maybe mid $xx. Wait a few years though and it should go up in value ten fold. There are tons of words like that still available. I have a big list right now waiting to be regged
