You might object that professionals excavate toacquire knowledge, not money. Moreover, ancient arti-facts are part of our global cultural heritage, whichshould be available for all to appreciate, not sold to thehighest bidder. I agree. Sell nothing that has unique(25) artistic merit or scientific value. But, you might reply,everything that comes our of the ground has scientificvalue. Here we part company. Theoretically, you may becorrect in claiming that every artifact has potential scien-tific value. Practically, you are wrong.
