THat chimney looks good on the outside and is most likely more than suitable for your coal stove or insert. DO NOT let a dealer talk you into the extra expense of a liner that could possibly fail in a few years. Fly ash from coal contains sulfur that combines with moisture to create sulfuric acid. This acid (yes - battery acid) can and most likely will reek havoc on a liner. Some people have had good outcomes with liners, some haven't... Flue gases from a coal appliance are much cooler than a wood fire.
Get a chimney inspection from an unbiased, coal experienced person if yer concerned about it. Otherwise you can inspect it yourself. Chimney gurus - please advise
To me, a liner is like putting a diaper on a toddler that's already potty trained
