Welcome to the world of undervalued Malay kerises.
Well, I thought the keris on the right had a mighty unusual hilt for a Malay keris, and the pendoko was probably made somewhere outside the Peninsula. The blade looks like it travelled from elsewhere too. So the 2nd keris is not quite a traditional 'thoroughbred' N. Malayan keris.
The one on the left is the one that makes up most of the value I'd say, but you'd probably notice that the fullness of the hilt (Terengganu) does not fully match the almost 'gaunt' and angular looking top sheath. The wood is very good for sure, same for the batang, but its just the form and the angle at which the hilt (and therefore the peksi) joins the sheath that makes the whole combination a bit disjointing in terms of aesthetics. I'd hazard to say that this piece may be a put-together, especially with the ganja sticking tentatively out of the sheath, and not in a clear strong manner.
So don't feel too bad for yourself, Sajen.
there are better ones, just keep your eyes peeled, and go for "one-shot one kill" bidding.
