This is a good 3 letter tld. It is 6 years old with 2 drops. It could easily be sold to a number of organisations with those 3 letters as an acronym It has moderate search traffic and low-moderate search competition 3 letter domains tend to be more valuable with a vowel in them, it improves their memorability and they are more transferable. However due to the limited number of 3 letter .coms available (17,576) it has a high value based on that alone. At auction I think you could expect $3000, if you contact worldwide businesses and organisations who are called SJN then it could maybe fetch $7500+ PM me if you would like more details or want to know how to sell it.
