1969 cent Weak D mintmark !

[Alexdonjohan]

On this case of 1969 D Lincoln one cent I got here a very small and weak mint mark as I never seen small mint mark such this except 1922 weak mint mark ..i compared this penny to other pennies of the same year 1969 D and I checked many pics on the Internet and all of them have normal mintmark or bigger size D ...also I compared it with my other 1969 d cents .. I'm pretty sure the mintmark in the pics looks bigger even because when I look at the penny here I can hardly see it !
I would like to know is this mintmark size is normal ?
one important point here is the reverse has a die cracks circle and I'm trying to add the pic of the crack to this topic
Thank you .

All of the mintmarks were hand punched during this time frame. The weaker looking mint mark is probably the result of a light punching by the technician at the Mint. A lighter punching would also result in a smaller looking mintmark because it wasn't deep enough into the die to strike up properly. Although you may not see too many of these, it is not considered anything special. Sorry.
