1986 D LMC DDR, Partial Column In Last Bay (11th Bay)

Just found this one. Nothing close to this is listed. I'm not all into minor doubling like this but thought it to be pretty neat. Don't think it's a die gouge based on the shape, the location in relation to and adjacent to the last column, and this coin doesn't exhibit any noticeable zinc rot. Don't think it's a blister either because this coin, even though it's not pristine, does not have any other readily visible plating blisters except maybe two small ones on the obverse. What do you think. Thanks!
