I think the hilt on the first one is Javanese as well, not Madurese. You could have the sheath tested, but i'm willing to bet that there is no silver content there, just a white metal (mamas). I like this keris and dress. I often see mendaks sold on eBay if you're looking.
I will reserve comment on the second keris, but personally wouldn't spend too much time or money on a selut for it.
