I finished going through my quarters and found the following two. The 1985P has a minor die clash on the back (found same type on maddieclashes.com but different year) and the 2015P Kisatchie with interesting letters.
1985-P quarter
If you look under the eagle's wings you will see the outline of Washington, the first picture is upside down, but still under the wing, second picture show what was called top of Washington's nose. The back looks the same as the following atypical die clash on maddieclashes.com (ADC-25c-1988-01 bottom picture)


2015 P Kisatchie
I saw this coin and thought how interesting this is. I will post three pictures showing the find. Looking at the first picture the K and I have the upper part of the letters to the left of the full letters. In the second picture you can see the depth of the smaller upper K and in the last the upper I is not as strong as the K. This reminded me of the story "Error catches eye" by Ken Potter
