I think probability of resale of this .co domain is rather small. Only in case of particular end user who heard of .co as alternative to .com, needs to abbreviate his actual domain, and does not have money for .com (and at the same time that end user has not heard of new gTLDs which can provide plenty of alternatives). It it resale, then 1-3k imo.
The fact that OAI in .com sold of 39k is driven by LLL investment trends in .com, it can not be applied to .co.
