Beat Up ATB Quarters

If you just received them you could return them to the mint for credit and try again. Water spots are one thing, but coins with scratches are another. But you have remember that they are circulating quality coins and you do have to take you chances. However you don't have to accept inferior coins when you are paying a premium for them. I would return the coins for credit and try again.

Contact the mint first and explain that you are unhappy with the quality and want to return them. If you've just received them it should be no problem.

It's to be expected for bagged or rolled coins. From the roll I got, I only saved a handful that I thought would be suitable for putting in an album.

Mechman, hear you loud and clear. Sure they are nice but I agree water spots ( some sort of cleaning fluid ), dings, scratches, hits, you name it.
As Cap.Fwiffo does, go through and save some of the best.
I'm sitting on all the 2010 and 2011 rolls and trying to figure out what to do with them after paying the mints high buck price.
I did buy the El Yunque P & D to see if they improved IMHO, no.

I think these NCLTs are washed with a liquid dishwashing detergent before they are bagged or counted into rolls. I have seen the same kind of spotting the OP is concerned with on recent Mint sealed uncirculated Mint sets. I believe the problem is the dryer is too low and leaves water stains. It shows up most often on cents and the golden dollars and are really ugly.
