I am not an errors guy, but I do find the missing edge lettering kinda fun. I have a Washington. I’ve been considering putting a set together with many of the other presidents.
As mentioned, it is not a good idea to use the tweezers to hold the coin. You might damage the coin. JP's Corner has "Koin Tongs" available that are plastic and less likely to damage a coin. The tongs have a locking mechanism which allows you to stand the coin on its edge so that you can use both hands to operate your camera and eliminate blurry photos (like yours!) ~ Chris
