vinyl records

Which versions of Johnny Yip's vinyl records are more noteworthy?

Versions related to TV drama theme songs,early releases,complete lyric sheets,well-preserved covers,and clean vinyl are all worth having photographed for an appraisal.

Can they be appraised together with male singers like Roman Tam and Michael Kwan?

Yes. The records of these singers are from similar eras,and their fan bases are similar,so appraising them in the same batch will be more accurate.

Can records with incomplete covers or lyric sheets still be bought back?

You can inquire first. Incomplete items will affect the appraisal,but it still depends on the version,tracklist,and condition of the vinyl itself.
