Is it a real Keris?

[A. G. Maisey]

The blade shown in post #10 is old, I do not have an opinion on how old, but definitely pre-WWII.

Old keris often have very thin blades, as do keris of ordinary quality.

More recent keris often have heavier blades.

Whether a keris is old or recent has very little to do with its quality or its desirability.

Certainly an older keris of high quality has a much higher value than a recent keris of high quality. It is also certain that some collectors prefer older keris, but many collectors focus on the artistic aspects of the keris, & these collectors will have collections that contain large numbers of more recent keris.

Just because a keris has some age, that does not necessarily mean that it is very desirable for all collectors.
