Is this a common error Few issues with this dime maybe die cracks and polishing error by torch both sides or maybe something else any help appreciated
It is hard to say without clear photos. But what I can see look like a damaged planchet. It could be Struck Through Debris.
I think you have two things going on, I think you have a strikethrough on the torch itself and the leaf ER. The horizontal lines in the field next to the torch are probably feed finger damage to the dies.
Conder101 - I agree It's definitely Feeder Finger scrapes; I agree the struck thru area is different and probably a separate occurrence. These FF marks are fairly common on mostly Dimes and Quarters from the past 20 years or so, although they are known on Dollars too,.
