The different texture sound the inside of the coin seems to be done during the minting process. Look how close to the head it is. The "In God We Trust" is smeared upwards. The 20 in 2014 is almost flat (hard to tell that tho in this pic). Can't tell if doubling in the "Liberty' or smeared a bit. The rims are still high possibility a bit higher than normal. Even the back is like this . Of course with most circulated coins there are some scratches done after the mint. Thoughts?
Die deterioration Denise. Sorry, not an error. Those outward bound "flow Lines' you see confirm this, so everything else you see is deterioration also.
