Flavio, age is ALWAYS a tricky thing to determine with keris, especially judging it merely from a few bad ebay photos. I would say, though, that in spite of Ricks concern about high contrast pamor material that your keris is at least 19thC. My guess would be early to mid century. Rest assured you got a pretty good deal on this one. Between you and Lew's recent purchase it's giving us poorer keris collectors so hope.
