Some coins were loose and some were in stapled cardboard.

These are 720 dpi scans, what's the best way to take pictures of coins?

I have an estate collection to liquidate and I'd like advise on "uncirculated" coins. On the examples below is this considered "uncirculated"? I know these coins in particular are not not valuable but I'd like to be able to identify uncirculated coins before going through the whole collection.
