Well, hmmm.... that is hard to say, only because considering the economy right now... But, Arabians with nice bloodlines like that, and especially those that are pure (as in pure Polish or straight Egyptian) usually bring a higher price. And just by looking at his pictures I'd say he is really put together very nicely, he would have brought at least a few thousand as a green broke gelding, if not more.

*El Mareekh was very highly thought of. If I remember right, he died tragically, and way too soon, from blister beetles (blister beetles in the hay).... I think.... I should look that up. His owners had previously lived in WI (where I live), I had been to their farm many years ago, before they got *El Mareekh.
