Under Weight Planchets

[accumulator]

Recently i bought 3 coin ,2x2cent & a 1 cent,struck on under weight planchet, just wondering what others thoughts on these would be ?

The 1st one is 3.5 grams





the 2nd is 3.6 grams.






& the 1 cent is 1.5 grams

They all look real enough.  The last one is struck on a split planchet.

Thanks Mark,i figured the 1 cent was a split planchet,any idea how the 2 cents would be so under weight,right at the end if the sheet rolled too thin ?
