I am showing you three different 1969 coinsI'm also showing you 1958 philly also there's this 1970 d with something above the date. Im seeing the shadows from what appears to have been a good dbd die on the 69
It looks like you have some minor machine doubling on the 9 and 6 in one photograph. It may be too minor to add much to the value but is a keeper for yourself because you identified it. Anything you find yourself is a treasure. The 1970 coin just looks like it took a hit from another coin in someone's pocket or a similar situation. I really don't see anything on the others to speculate on but keep up the hunt.
No no no no no. Put the scope/camera on the shelf and buy some books or visit some web pages such as: http://www.doubleddie.com/144801.html
