The 3 Char (LLL.IN & NNN.IN) are all registered. There is demand for 3 Character IN names and supply has dried out.
Based on the following information (Reference: http://www.3character.com/price-guide.html) Pricing Guide for 3-Letter (Composed Of Letters or Numbers Only) Domains:
Current Observed Minimum Wholesale Price (regardless of letter combo) as of December 1, 2015:
3-Letter .com - $19,000
3-Letter .net - $1250
3-Letter .org - $400
3-Letter .info - $15
3-Number .com - $110000
3-Number .net - $6000
3-Number .org - $800
3-Number .info - $275 Premium letter only domains tend to fetch a 500% to 600% premium (or more) over the Minimum Wholesale Price.
I would rate the .IN domains between .ORG & .INFO (more towards .ORG price)
Based on these numbers, I would say 3-Letter.IN wholesale price to be $300 and 3-Number.IN Wholesale price to be $600
