Does it look damaged? Dented or something? They are not that sensitive to damage, the can would have to be dented or split to damage the interior. Its not filled with glass or anything. I've taken them apart. They are typically very thin wound up metal foils, separated by an insulating layer of something like paper. Its complicated to test one and know its exact value. They usually either work or they don't. With an old analog multimeter, you could short the cap, then hook it up on ohms. It should swing hard as the cap charges, then go to zero ohms as it should not conduct dc. If it has no charge, it should not read any conduction with a digital multimeter set to say 1 meg ohms range. Your sweaty fingers will conduct at that range.
