Unsure that it's quantifiable like this (a minimum amout to be worth anything) for valuation purposes, IMHO ... indeed, those OVT numbers look pretty decent but I think the answer(s) will depend based on other factors and perceptions, subjective to each domainer (or appraiser).
Just my two sense, obviously both ".CC" and ".WS" are amongst the weaker extensions in reselling, and only a tiny fraction of any respective ".COM", in my view.
Can you post the actual domain names - with the respective extensions and OVT counts. Perhaps some Google numbers, as well to provide a bit more insight?
All the best!
