Magnolia error or return to mint?

FC57Coins

Whilst playing with my camera to get good pictures like Russ gets, I noticed that on my favorite Mississippi proof quarters there is a comma shaped imperfection in each of my 5 proof quarters. If you look at the picture below, it is between the first S and the flowers at 7 O'Clock from the 1 on 1817. (to the right of that is a piece of lint I think) Anyway, do other folks have this imperfection? Should I send the coins back to the mint and ask for new ones?

Thanks,

Frank
