How much is this worth?

I've got a domain but its one of the new tlds

Consider this,
domain is KeywordPart1.KeywordPart2
KeywordPart1(space)KeywordPart2 has 10,000 avg monthly searches, $1 avg cpc
KeywordPart2(space)KeywordPart1 has 49,000 avg monthly searches, $1 avg cpc

The domain name is highly brandable but as I stated,one of the new tlds

Can it carry any value or not worth reg fee?

Noone can tell you anything with the info you provided.. those keywords could be anything

the keywords are related to gambling

i think that new tlds it's very bad way for selling
if you want grow brand - new tlds can be good, but just reselling, don't sure

There are many websites where you can find the worth of the domain which you want to find. I suggest you the site named "siteprice" where i could find the answers are reliable. The link for that website is "http://www.siteprice.org".

I am no expert on this but let me present a very straight forward fact. I believe you have what is called a domain hack (depends on what your keyword part 1 and 2 are). How many keywords do you think there are, which are similar? How many of those are ranking? I guess not many. If your domain is brandable it means that people will remember your name. This ultimately does not mean anything. Your site's content/service and look n feel makes your visitors come back. You might or might not get some help from the silly googlebot, but be your own judge please?
