I picked up 25 50 cent pieces from my local bank, they had been deposited and the teller remembered that I collected coins and offered them to me. All were in uncirculated condition and I assume that since I got 25 of them that they were from the same roll.
Upon inspection under a microscope I discovered that 20 of them had a die chip on the top of the zero of the 50. 5 coins did not show the die chip.
I have added pics of 5 different coins that display the die chip for your review.
Does anyone have similar coins?
If 20 of 25 coins show the die chip does that make the other 5 more valuable?

Minor die chips do not usually add or subtract value from a coin.
As far as having 20 out of 25 with chips do not make the ones
without more valuable. There were 750,000 of these produced
and the vast majority would not have that die chip.

There's also some MD or die deterioration on some of them, again not adding any value, and maybe subtracting. The mint is not in the business of making flawless products, only punching out as many as they can, as cheaply as possible so they can still be accepted as monetary examples.
