Found two 1964 penny's and both look different. Is there anything special?

I noticed that both look different and the D mint penny is really more detailed. I was wondering if there a good find? I'm new at collecting coins but I'm starting to enjoy this. Thank you all for this new hobby of mine.

Nothing really special that I can tell-- it just looks like the one on the left has seen more wear than the other one.

 

I recall reading a thing Found in Rolls @ Coin World + his own site. its was about LMC Cent 1964-D Mint Mark maybe having 2 sizes other than that.
your photo could be just one struck with a new die + 1 struck with a worn die.
But I am No expert!!! :yes: on anything But me,also 56yrs of collecting do know a few thing. but recalling the who what + were is getting harder with each passing Day.
