Tell him to be careful, as these pop up on eBay VERY often, and tend to sell for only a few dollars each if you are patient. Also, I have heard some reports that not all of the MOP's that are being referred to as "old, rare" are actually either (not to say that the ones he is interested in are not authentic). Many appear to be modern remakes of the originals. I have seen the same thing with the MOPs with Chinese symbolism as well....
