Reg. fee: Domain sounds like it was randomly generated (no niche is filled) and domain utilizes numbers. If it was < 5L and was alphabetical characters only, this may be worth something higher than reg. fee.
My advice is to look for the generic domains (e.g. HotSexyDates.com, AdultEducationAustralia.com, etc.) instead of the 1-5L market, as the barrier for entry is usually not as low. In addition, please read up on the "Domain Beginners" section of this forum, as well as conducting more research.
Hope this helps,
