Thanks, everyone! I'm pretty excited with this find. The first half of this bank box yielded this 1972 coin, a
Cud and a 1998
Wide AM. Coop, your pictures are amazing and extremely helpful.
twslisa, I use "Plugable USB 2.0 Digital Microscope with Flexible Arm Observation Stand" for $35. For the pictures above, I needed to hold the coin, as the stand doesn't work too well (in my opinion). For the last picture, I had to supplement the light from the microscope with a flashlight (and that it why there is the shadow at the top).
