Munktiki Ona Keko #5 of 100

I am no tiki expert, but as I was unpacking boxes I found this old tiki of mine. Is this collectible? I see munktiki is still around. I love this tiki, it feels great in my hand but if it's worth something I guess I'd consider selling it. Can this board give a tiki novice any info on if it's even worth anything?

It looks like the last one someone recorded sold for $50: http://www.ooga-mooga.com/cgi-bin/all/mug.cgi?mode=view&mug_id=192
