The "ridge" you are referring to on this cent is not an error. It is caused by a worn out obverse die. It is common on many of these plated cents from the 80's and 90's as the Mint notoriously overused their dies throughout this time period.

The journals are used by people who wish to document their collecting journey and are not "threads" commonly used in the forum. This would be the reason for a lack of comments. This would better be posted in the Newbie section of the forum where questions such as this are posted and seen by more people.
