I would personally prefer an untouched keris when it will be possible to get it in a not rusted condition and with solid dress. I have a very few of this in my collection. The most have received a good cleaning and new staining of the blades and many times also restore work by the dress. But to collect keris with a complete rusted blade and a dress in sad condition is strange IMVHO. But your pictures show many well kept keris so it seems that there in Malaysia the collectors have different views about this topic.
