Need Help Identifying Quarter

Please always show us the whole coin, both sides. Thanks.

Well it can't be a class 4 as these are single squeeze dies and the doubled dies on these are on the central areas. But kudos for looking in the right areas of the devices. But it is still Machine Doubling or coin contact on those areas.

Contact marks splash the metal leaving waves. But the flattening, push of devices with other coins will bump the devices and alter the coin. The locations mention are on the cross bar areas. Obverse: Ears and on the side of the motto:

Note the raised areas on the fields or devices? That is hub doubling on the single squeeze dies.

Side by side of Machine Doubling reducing the size of the devices. On a doubled die they are enlarged and show normal device distortion.
Reverses. Where the crossbars meet is the target areas to look to find the DDRs. The post 1999 (some earlier) coins with the single squeeze process are all located in the total opposite area. Most people don't know where to look and I'm trying to point out the areas where they could be hub doubled. When in doubt, Check the Wexler files for the locations listed. Always better to know what to look for rather than guess. You will save time know where to look.
As you mentioned lump, I feel you are talking about die chips. They are not part of hub doubling.

Here is the home page for these files. It is a very good read for all variety coins. (no errors are listed there just variety coins)


CoopHome: What is the the target area for the ATB Quarter reverses for doubled dies?

They are doubled dies. The locations for these are different than the previous multi-hub dies. The DDR's are in the central areas of the design. Same for Nickels and dimes. They are in the same central areas.
Dimes:


Nickels:


Obverse on nickels are even harder to spot:




The DDR on the Memorial cents with the bar on either side of the middle bay:
Those were the cent DDR's back then. (Ended in 2008 for the Memorial cents)
Central areas for the 2009 DDR's on cents.
