There is a small area on the top surface where there is residue from the black covering of another case.  Originally this was more noticeable but I have cleaned most of it off. However I have left what's remaining as I don't want to risk adverse wear on the green leather covering, but it could be potentially removed further if done with care.  Other than this the case is in good condition.

The COA has a tiny impression mark on it.

Please note that this certificate and case were separate when acquired and I have since put them together as both are for three-coin gold proof sovereign sets and only the COA itself is dated.  However I believe that the correct colour case for 2000 was red so this green one may in fact have been for a different year originally.  But as I say there's nothing on the case itself to indicate a year so they go together fine regardless in my opinion.
