The value would depend in part on the renewal fee - is this a domain with a premium renewal fee?
Assuming it is not, the India24 is really nice - I can see a large corp wanting to brand itself under that term. However, .tv is really weak in India - so maybe the domain would be better suited for something aimed at NRIs.
India24 could make a nice one, as appointed by Jeff. However, I don't think it's worth low $xxx. Maybe a high $xx, like $80.00? I don't see what the 24 would be used for, however, I do like your choice to do .tv, but as Jeff said, " .tv is weak in India". It makes sense to make .tv, but as Jeff pointed, try to aim for a better one. Waiting a few years would help, too.
A lot of large companies brand their urls with 24, meaning 24 hours per day. I think that the 24 suffix works well with "India" and it sounds like something a large company might use.
Still, I think .tv is a nice extnesion, but hard for domainers to make much money with it.
