1820 Coronet head Large Cent Fine some corrosion Reverse rotated 45 degrees

Description

1820 large cent with small date graded fine
I obtained some nice coins from a collector and am listing them here in uncertified condition
I was a coin collector as a kid and the grading marked on the holders look correct to me
I carefully removed the coin for photo then placed it back in the original holder`
This coin has some corrosion and no attempt has been made to clean it
I also noticed the the front and back are not lined up properly,  appears to be off by about 45 degree, not sure if that is normal or even matters
