No, it's a plating bubble/blister. Early Zinc cents are notorious for them. Occasionally, the show up as long streaks. It doesn't have any additional value
Yep - improper copper plating bubble(s). Still easily found, and 97% of them don't carry a premium, unless it covers a large area, or there are many many of them. Your's is about 'average' for the long shaped bubble/blister. It's an interesting conversation piece, but as mentioned above, has no numismatic error premium like that, imo.
