Bosko Moai Mugs - questions

I have these two Moai mugs that I bought from Bosko personally back in the mid 90's, and I've never seen them anywhere else. Does anyone have any background on these (Bosko?), particularly on their rarity and value. I would consider selling them if they were highly desired.

Maiaria, I would be willing to trade an Orchids of Hawaii coconut mug for one of these, that way you will have a little variety :wink:

I don't know how much the big ones fetch, but I bought a smaller one on ebay not too long ago for less than $30.
