Got 3 Lincoln Cents I Could Use Some Opinions On Please

Just Need Some Input On If These Are Errors On These Three Coins Or Just PMD?

The Following Is A Brief Rundown Of What Errors I Thought It Could Be And Why On Each Coin. Also Feel Free To Be As Blunt As You Like Debunking My Theories I Actually Prefer It That Way So The Next Time I See A Similar Coin I Can Quickly Narrow Down What Errors It Cant Be Which Overall Leaves Me With A Much Smaller List Of Real Possible Errors.

1973 S - This One Looks Like It Has A DDR If You Look At The Statue And The Memorial Building There Is Strong Doubling But I Did Not See Any DDR Listed On Any Of The Various Sites For This Particular Year. Also I See Imprints Everywhere Of Letters Are These Just Die Clashes?

A Few Other Things I Noticed Are The FG Initials Look Too Close Together, There Is A Partial Collar Error (Let Me Know From My Picture If I Am Wrong) And It Is Actually A Misaligned Die, I Am Still confused On The Subject. Lastly There Seems To Be A Improper Alloy Mix Going On With The Strange Orange Tint Or Is This Just Environmental Damage?

1978 D - Now On This Coin I Can See Doubling On Both Sides Of The Coin Especially On Lincolns Nose And Ear Lobe So I Ruled Out A Doubled Die Error As Doubling Usually Only Effects One Side Of The Coin Right?

So I Switched My Thinking To Maybe This Coin Has Been Struck More Than Once And I Notice Some Possible Evidence To Back That Up. First I See What I Think Is A Collar Line Imprint On The Right Side Of The Obverse In Line With The T In Trust And A Bit To The Right Of The 8 In The Date.

Also It Appears The Statue From The Memorial Building Is Partially In Every Bay. Lastly I See Imprints Of Letters Everywhere Especially Above One Cent And It Does Not Look TO Match For A Die Clash Error And Damage To The Rim Maybe Due To The Pressure Of Multiple Strikes.

1999 - I Cannot Decide If This Coin Has A Lamination Error, PMD Or Has Been Struck Multiple Times. Lincolns Nose Is So Damaged I Thought Maybe It Was From The Pressure Of Multiple Strikes, Severe Lamination Peeling Or Just Plain Old PMD.

The Other Thing I Could Not Figure Out Is Why There Are Imprints Of Multiple 9's Above The Date And Other Lettering Impressions All Around The Coin. This Coin Too Has A Partial Collar Error (I Think).

The 1999 and 1978 Coins Weights Are Spot On And The 1973 Is Within Tolerance Weighing 3.04.
