Well pennies of last few decades have slightly different variances in the design. And different qualities of strike. So pennies of a certain year tend to have unique characteristics compared to other years. Also pennies went to zinc from copper in 1982 so there's is that too. Zinc pennies age poorly compared to copper ones. That is what Meow has noticed doing CRH for a few years.
Are these considered common issues for these years or a variety let me know what y'all think and I'll let y'all know I what I see
Meow does not think you have anything of note there. Meow looks for cuds and die chips in Zincolns (fairly rare). And RPMs for older copper issues (50s-60s). Also pennies made in the last 3-4 years have had doubled dies in Lincoln ear; Meow has a small pawful of those.
89 front clipped on collar cud by L liberty and ibe error and back shoulder in field possible d mint mark and back 89 a double in one and fg and also extra columns
78 front cud die mark by 8 and collar and die mark in front of nose and by forehead seen that error before something and coming in contact with edge of other coin
78 something about the ear doesnt look right oh 2014d in god we trust second look 97 letters trust and strike behind ear
I'm not seeing any clips or cuds. The '78 is a rim ding, it's was struck on the rim so it's damaged. This is a large cud This is a small cud This is called a clip but the correct term is an incomplete planchet
