Can anyone explain the significance of the small round circle (apparently with an "x" through it) that appears between the right silhouette and the center silhouette on the $100 Who chips? It does not appear on the artwork provided on the Hard Rock site. I thought mine was just a printing error, but all of the chips I've seen listed so far on eBay have it as well. Is it some type of error? Does it have some type of artistic significance?

Sorry, I don't have a scanner up and running. It is obvious in the following auctions (not mine)
