Hey Steve; There ARE three sides to a coin. Obverse, Reverse and Edge. Those coin collectors who know about lettered edge coins struck prior to 1836 know all about the 3rd side (the edge).... and why concealling the 3rd side from view in a slab was so damn stupid. (Sorry, couldn't resist the open opportunity).<g>

BTW; there are the same three sides to a chip as well, especially if one wishes to view the stackables edges.
