I am following the ccc.com market since 2012. It is really hot right now!
If you list it a namejet with no reserve (yes), it will attract lot of bids and can sell between $900 and $1,200.
It's sounds a good idea to sell those type of domain names but we should also understand that the people that are buying them are also investors. The 3 Letter and 3 Number market is burning hot and I belive that the ccc.com is just about to explode.
LNN and LLN .com are the most valuable 3 characters (Numbers and Letters) domain names.
A premium Letter combined with premium numbers = High value
In this case
Ultra premium letter "S" and number "7" but the bad "4" (Means death in china kinda like the number 13 for us).
If you need the money, take it.
If you are ready to wait, you may be able to sell it for $3,000 or more with a BIN on sedo.
