I don't really know how rare it is or how much it costs nowadays, because I could never find another one for sale. It's a HUmar Statue, from Phantasy Star Online.
All I know is that they were only sold on Sonic Team Japanese website and they were, apparently, limited at first. I'm not really sure on that.
I bought it on November 2004 and it cost me 150,95 plus 23 USD shipping to Brazil.

Found a little more information, for those interested (aka, me). It used to be sold for 12,000 yen, but later it was on sale for 8,000 yen

I didn't know they eventually made another two statues. The HUnewearl looks nice, but I prefer the HUmar.
About how many were built, according to
http://www.sonicteam.com/pso/goods/psost01_01.htm, at first, only 500 were made. The shitty Google Translation says that "Sales reached 500 in number and we will still not be terminated.". Mine has "0570 of" on the box, so there's that (I don't know Kanji and the rest of the phrase doesn't make any sense to me).
